General Description The MAX9100/MAX9101 micropower comparators are optimized for single-cell systems, and are fully speci- fied for operation from a single supply of 1.0V to 5.5V. This ultra-low voltage operation, 5µA quiescent current consumption, and small footprint make the MAX9100/MAX9101 ideal for use in battery-powered systems. A wide-input common-mode range that includes the negative rail and rail-to-rail output swing allows almost all of the power supply to be used for sig- nal voltage. In addition, propagation delay is less than 4µs, and rise and fall times are 100ns. The MAX9100 features a push-pull CMOS output stage that sinks and sources current with large internal output drivers that allow rail-to-rail output swings with loads up to 5mA.The MAX9101 has an open-drain output stage that makes it suitable for mixed-voltage designs. The MAX9100/MAX9101 are available in tiny SOT23-5 packages. ________________________Applications Single-Cell Systems Pagers Closed Sensor Applications Battery-Powered Instrumentation Portable Electronic Equipment Portable Communication Devices ____________________________Features • Ultra-Low Voltage: Guaranteed Down to 1.0V • Low Quiescent Current: 5µA • Optimized for Single-Cell Battery-Powered Systems • Wide Input Common-Mode Range • CMOS Rail-to-Rail Output Swing (MAX9100) • Open-Drain Output (MAX9101) • 4µs Propagation Delay • High Output Drive Capability: 5mA Sink and Source (MAX9100) • No Output Phase Reversal for Overdriven Inputs • Available in Tiny SOT23-5 Package M A X 9 1 0 0 /M A X 9 1 0 1 +1.0V Micropower SOT23 Comparators GND IN-IN+ 1 5 VCCOUT MAX9100 MAX9101 SOT23 TOP VIEW 2 3 4 Typical Operating Characteristic 2 4 3 6 5 7 8 -40 10-15 35 60 85 SUPPLY CURRENT vs. TEMPERATURE M A X 9 1 0 0 t o c0 1 TEMPERATURE (°C) I C C ( µA ) VCC = +5V VCC = +2V VCC = +1V 19-1808; Rev 1; 1/07 Ordering Information PART PIN- PACKAGE TOP MARK PKG CODE MAX9100EUK-T 5 SOT23-5 ADOR U5-1 MAX9100ESA 8 SO — S8-2 MAX9101EUK-T 5 SOT23-5 ADOS U5-1 MAX9101ESA 8 SO — S8-2 Pin Configurations Pin Configurations continued at end of data sheet. ________________________________________________________________ Maxim Integrated Products 1 Note: All devices specified for over -40°C to +85°C operating temperature range.

M A X 9 1 0 0 /M A X 9 1 0 1 +1.0V Micropower SOT23 Comparators 6 _______________________________________________________________________________________ Detailed Description The MAX9100/MAX9101 are low-power and ultra-low single-supply voltage comparators. They have an oper- ating supply voltage range between +1.0V to +5.5V and consume only 5µA of quiescent supply current, while achieving 4µs propagation delay. Input Stage Circuitry and Rail-to-Rail Operation The devices’ input common-mode range is fully speci- fied from 0 to (VCC - 0.2V), although full rail-to-rail input range is possible with degraded performance. These comparators may operate at any differential input volt- age within these limits. Input bias current is typically ±5nA if the input voltage is within the specified com- mon-mode range. Comparator inputs are protected from overvoltage by internal diodes connected to the supply rails. As the input voltage exceeds the supply rails, these diodes become forward biased and begin to conduct. Consequently, bias currents increase expo- nentially as the input voltage exceeds the supply rails. True rail-to-rail input operation is also possible. For input common-mode voltages from VCC - 0.2V to VCC, the input bias current will typically increase to 800nA. Additionally, the supply current will typically increase to 7µA. Otherwise, the device functions as within the specified common-mode range. See graphs in the Typical Operating Characteristics. Output Stage Circuitry The MAX9100/MAX9101 contain a unique output stage capable of rail-to-rail operation. Many comparators consume orders of magnitude more current during switching than during steady-state operation. However, with this family of comparators, the supply-current change during an output transition is extremely small. The Typical Operating Characteristics graph Supply Current vs. Output Transition Frequency shows the min- imal supply-current increase as the output switching frequency approaches 100kHz. This characteristic reduces the requirement for power-supply filter capaci- tors to reduce glitches created by comparator switch- ing currents. This feature increases battery life in portable applications. Push-Pull Output (MAX9100) The MAX9100 has a push-pull CMOS output. The out- put stage swings rail-to-rail under no-load conditions. External load drive capability varies with supply voltage.

M A X 9 1 0 0 /M A X 9 1 0 1 +1.0V Micropower SOT23 Comparators _______________________________________________________________________________________ 7 Open-Drain Output (MAX9101) The MAX9101 has an open-drain output, which can be pulled up to +6.0V above ground independent of the supply voltage. This is typically used with an external pullup resistor, facilitating interface between mixed logic voltages. Alternatively, multiple open-drain comparator outputs can be connected in a wired-OR configuration. Applications Information Low-Voltage Operation: VCC = 1V The minimum operating voltage is +1.0V. At lower sup- ply voltages, the input common-mode range remains rail-to-rail, but the comparator’s output drive capability is reduced and propagation delay increases (see the Typical Operating Characteristics). Internal Hysteresis Hysteresis increases the comparators’ noise margin by increasing the upper threshold and decreasing the lower threshold (Figure 1). This hysteresis prevents the comparator from providing multiple poles when driven with a very-slow-changing signal. Additional Hysteresis These comparators have 1.0mV internal hysteresis. Additional hysteresis can be generated with two resis- tors using positive feedback (Figure 2). Use the follow- ing procedure to calculate resistor values: 1) Calculate the trip points of the comparator using these formulas: and VTH is the threshold voltage at which the comparator switches its output from high to low as VIN rises above the trip point. VTL is the threshold voltage at which the comparator switches its output from low to high as VIN drops below the trip point. 2) The hysteresis band will be: VHYS = VTH - VTL = VCC 3) In this example, let VCC = +5V and VREF = +2.5V: and 4) Select R2. In this example, we will choose 1kΩ. 5) Select VHYS. In this example, we will choose 50mV. 6) Solve for R1: where R1 ≈ 100kΩ, VTH = 2.525V, and VTL = 2.475V.
