FN9160 Rev.4.00 May 5, 2008 ISL6614A Dual Advanced Synchronous Rectified Buck MOSFET Drivers with Pre-POR OVP DATASHEETThe ISL6614A integrates two ISL6613A MOSFET drivers and is specifically designed to drive two Channel MOSFETs in a synchronous rectified buck converter topology. These drivers combined with HIP63xx or ISL65xx Multi-Phase Buck PWM controllers and N-Channel MOSFETs form complete core voltage regulator solutions for advanced microprocessors. The ISL6614A drives both the upper and lower gates simultaneously over a range from 5V to 12V. This drive voltage provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. An advanced adaptive zero shoot-through protection is integrated to prevent both the upper and lower MOSFETs from conducting simultaneously and to minimize the dead time. These products add an overvoltage protection feature operational before VCC exceeds its turn-on threshold, at which the PHASE node is connected to the gate of the low side MOSFET (LGATE). The output voltage of the converter is then limited by the threshold of the low side MOSFET, which provides some protection to the microprocessor if the upper MOSFET(s) is shorted during startup. The ISL6614A also features a three-state PWM input which, working together with Intersil’s multi-phase PWM controllers, prevents a negative transient on the output voltage when the output is shut down. This feature eliminates the Schottky diode that is used in some systems for protecting the load from reversed output voltage events.

ISL6614ADescription Operation Designed for versatility and speed, the ISL6614A MOSFET driver controls both high-side and low-side N-Channel FETs of two half-bridge power trains from two externally provided PWM signals. Prior to VCC exceeding its POR level, the Pre-POR overvoltage protection function is activated during initial startup; the upper gate (UGATE) is held low and the lower gate (LGATE), controlled by the Pre-POR overvoltage protection circuits, is connected to the PHASE. Once the VCC voltage surpasses the VCC Rising Threshold (See “Electrical Specifications” table on page 5), the PWM signal takes control of gate transitions. A rising edge on PWM initiates the turn-off of the lower MOSFET (see “TIMING DIAGRAM” on page 8). After a short propagation delay [tPDLL], the lower gate begins to fall. Typical fall times [tFL] are provided in the “Electrical Specifications” table on page 6. Adaptive shoot-through circuitry monitors the PHASE voltage and determines the upper gate delay time [tPDHU]. This prevents both the lower and upper MOSFETs from conducting simultaneously. Once this delay period is complete, the upper gate drive begins to rise [tRU] and the upper MOSFET turns on. A falling transition on PWM results in the turn-off of the upper MOSFET and the turn-on of the lower MOSFET. A short propagation delay [tPDLU] is encountered before the upper gate begins to fall [tFU]. Again, the adaptive shoot-through circuitry determines the lower gate delay time, tPDHL. The PHASE voltage and the UGATE voltage are monitored, and the lower gate is allowed to rise after PHASE drops below a level or the voltage of UGATE to PHASE reaches a level depending upon the current direction (See the following section for details). The lower gate then rises [tRL], turning on the lower MOSFET. Advanced Adaptive Zero Shoot-Through Deadtime Control (Patent Pending) These drivers incorporate a unique adaptive deadtime control technique to minimize deadtime, resulting in high efficiency from the reduced freewheeling time of the lower MOSFETs’ body-diode conduction, and to prevent the upper and lower MOSFETs from conducting simultaneously. This is accomplished by ensuring either rising gate turns on its MOSFET with minimum and sufficient delay after the other has turned off. During turn-off of the lower MOSFET, the PHASE voltage is monitored until it reaches a -0.2V/+0.8V trip point for a forward/reverse current, at which time the UGATE is released to rise. An auto-zero comparator is used to correct the rDS(ON) drop in the phase voltage preventing from false detection of the -0.2V phase level during rDS(ON) conduction period. In the case of zero current, the UGATE is released after 35ns delay of the LGATE dropping below 0.5V. During the phase detection, the disturbance of LGATE’s falling transition on the PHASE node is blanked out to prevent falsely tripping. Once the PHASE is high, the advanced adaptive shoot-through circuitry monitors the PHASE and UGATE voltages during a PWM falling edge and the subsequent UGATE turn-off. If either the UGATE falls to less than 1.75V above the PHASE or the PHASE falls to less than +0.8V, the LGATE is released to turn on. Three-State PWM Input A unique feature of these drivers and other Intersil drivers is the addition of a shutdown window to the PWM input. If the PWM signal enters and remains within the shutdown window for a set holdoff time, the driver outputs are disabled and both MOSFET gates are pulled and held low. The shutdown state is removed when the PWM signal moves outside the shutdown window. Otherwise, the PWM rising and falling thresholds outlined in the “Electrical Specifications” table on PWM UGATE LGATE tFL tPDHU tPDLL tRL tTSSHD tPDTS tPDTS 1.5V

Page 10

ISL6614Apage 5 determine when the lower and upper gates are enabled. This feature helps prevent a negative transient on the output voltage when the output is shut down, eliminating the Schottky diode that is used in some systems for protecting the load from reversed output voltage events. In addition, more than 400mV hysteresis also incorporates into the three-state shutdown window to eliminate PWM input oscillations due to the capacitive load seen by the PWM input through the body diode of the controller’s PWM output when the power-up and/or power-down sequence of bias supplies of the driver and PWM controller are required. Power-On Reset (POR) Function During initial startup, the VCC voltage rise is monitored. Once the rising VCC voltage exceeds 9.8V (typically), operation of the driver is enabled and the PWM input signal takes control of the gate drives. If VCC drops below the falling threshold of 7.6V (typically), operation of the driver is disabled. Pre-POR Overvoltage Protection Prior to VCC exceeding its POR level, the upper gate is held low and the lower gate is controlled by the overvoltage protection circuits during initial startup. The PHASE is connected to the gate of the low side MOSFET (LGATE), which provides some protection to the microprocessor if the upper MOSFET(s) is shorted during initial startup. For complete protection, the low side MOSFET should have a gate threshold well below the maximum voltage rating of the load/microprocessor. When VCC drops below its POR level, both gates pull low and the Pre-POR overvoltage protection circuits are not activated until VCC resets. Internal Bootstrap Device Both drivers feature an internal bootstrap Schottky diode. Simply adding an external capacitor across the BOOT and PHASE pins completes the bootstrap circuit. The bootstrap function is also designed to prevent the bootstrap capacitor from overcharging due to the large negative swing at the trailing-edge of the PHASE node. This reduces voltage stress on the boot to phase pins. The bootstrap capacitor must have a maximum voltage rating above UVCC + 5V and its capacitance value can be chosen from Equation 1: where QG1 is the amount of gate charge per upper MOSFET at VGS1 gate-source voltage and NQ1 is the number of control MOSFETs per channel. The VBOOT_CAP term is defined as the allowable droop in the rail of the upper gate drive. As an example, suppose two IRLR7821 FETs are chosen as the upper MOSFETs. The gate charge, QG, from the data sheet is 10nC at 4.5V (VGS) gate-source voltage. Then the QGATE is calculated to be 53nC for PVCC = 12V. We will assume a 200mV droop in drive voltage over the PWM cycle. We find that a bootstrap capacitance of at least 0.267µF is required. Gate Drive Voltage Versatility The ISL6614A provides the user flexibility in choosing the gate drive voltage for efficiency optimization. The ISL6614A ties the upper and lower drive rails together. Simply applying a voltage from 5V up to 12V on PVCC sets both gate drive rail voltages simultaneously. Connecting a SOT-23 package type of dual schottky diodes from the VCC to BOOT1 and BOOT2 can bypass the internal bootstrap devices of both upper gates so that the part can operate as a dual ISL6612 driver, which has a fixed VCC (12V typically) on the upper gate and a programmable lower gate drive voltage. Power Dissipation Package power dissipation is mainly a function of the switching frequency (fSW), the output drive impedance, the external gate resistance, and the selected MOSFET’s internal gate resistance and total gate charge. Calculating the power dissipation in the driver for a desired application is critical to ensure safe operation. Exceeding the maximum allowable power dissipation level will push the IC beyond the maximum recommended operating junction temperature of +125°C. The maximum allowable IC power dissipation for the SO14 package is approximately 1W at room temperature, while the power dissipation capacity in the QFN packages, with an exposed heat escape pad, is around 2W. See “Layout Considerations” on page 10 for thermal transfer improvement suggestions.
