General Description The MAX6381–MAX6390 microprocessor (μP) supervi- sory circuits monitor power-supply voltages from +1.8V to +5.0V while consuming only 3μA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. Reset thresholds are available from +1.58V to +4.63V, in approximately 100mV increments. Seven minimum reset timeout delays ranging from 1ms to 1200ms are available. The MAX6381/MAX6384/MAX6387 have a push-pull active- low reset output. The MAX6382/MAX6385/MAX6388 have a push-pull active-high reset output, and the MAX6383/ MAX6386/MAX6389/MAX6390 have an open-drain active- low reset output. The MAX6384/MAX6385/MAX6386 also feature a debounced manual reset input (with internal pullup resistor). The MAX6387/MAX6388/MAX6389 have an auxiliary input for monitoring a second voltage. The MAX6390 offers a manual reset input with a longer VCC reset timeout period (1120ms or 1200ms) and a shorter manual reset timeout (140ms or 150ms). The MAX6381/MAX6382/MAX6383 are available in 3-pin SC70 and 6-pin μDFN packages and the MAX6384– MAX6390 are available in 4-pin SC70 and 6-pin μDFN packages.

Detailed Description RESET Output A μP reset input starts the μP in a known state. These μP supervisory circuits assert reset to prevent code execu- tion errors during power-up, power-down, or brownout conditions. Reset asserts when VCC is below the reset threshold; once VCC exceeds the reset threshold, an internal timer keeps the reset output asserted for the reset timeout period. After this interval, reset output deasserts. Reset output is guaranteed to be in the correct logic state for VCC ≥ 1V. Manual Reset Input (MAX6384/ MAX6385/MAX6386/MAX6390) Many μP-based products require manual reset capability, allowing the operator, a test technician, or external logic circuitry to initiate a reset. A logic low on MR asserts reset. Reset remains asserted while MR is low, and for the reset active timeout period (tRP) after MR returns high. This input has an internal 63kΩ pullup resistor (1.56kΩ for MAX6390), so it can be left unconnected if it is not used. MR can be driven with TTL or CMOS logic levels, or with open-drain/collector outputs. Connect a normally open momentary switch from MR to GND to create a manual- reset function; external debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1μF capacitor from MR to GND provides additional noise immunity. RESET IN Comparator (MAX6387/MAX6388/MAX6389) RESET IN is compared to an internal +1.27V reference. If the voltage at RESET IN is less than 1.27V, reset asserts. Use the RESET IN comparator as a user-adjustable reset detector or as a secondary power-supply monitor by implementing a resistor-divider at RESET IN (shown in Figure 1). Reset asserts when either VCC or RESET IN falls below its respective threshold voltage. Use the following equation to set the threshold: VINTH = VTHRST (R1/R2 + 1) where VTHRST = +1.27V. To simplify the resistor selec- tion, choose a value of R2 and calculate R1: R1 = R2 [(VINTH/VTHRST) - 1] Since the input current at RESET IN is 50nA (max), large values can be used for R2 with no significant loss in accuracy. Applications Information Negative-Going VCC Transients In addition to issuing a reset to the μP during power-up, power-down, and brownout conditions, the MAX6381– MAX6390 are relatively immune to short duration nega- tive-going VCC transients (glitches). The Typical Operating Characteristics section shows the Maximum Transient Durations vs. Reset Comparator Overdrive, for which the MAX6381–MAX6390 do not generate a reset pulse.

a negative-going pulse applied to VCC, starting above the actual reset threshold and ending below it by the magnitude indicated (reset comparator overdrive). The graph indicates the typical maximum pulse width a negative-going VCC transient may have without causing a reset pulse to be issued. As the magnitude of the tran- sient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. A 0.1μF capacitor mounted as close as possible to VCC provides additional transient immunity. Ensuring a Valid RESET Output Down to VCC = 0V The MAX6381–MAX6390 are guaranteed to operate properly down to VCC = 1V. In applications that require valid reset levels down to VCC = 0V, a pulldown resis- tor to active-low outputs (push/pull only, Figure 2) and a pullup resistor to active-high outputs (push/pull only) will ensure that the reset line is valid while the reset output can no longer sink or source current. This scheme does not work with the open-drain outputs of the MAX6383/ MAX6386/MAX6389/MAX6390. The resistor value used is not critical, but it must be small enough not to load the reset output when VCC is above the reset threshold. For most applications, 100kΩ is adequate. Figure 1.
