MAX16160 High-Accuracy 4-Channel, Any-Input Supervisory Circuits General Description Benefits and Features The MAX16160 precision, four-channel supervisory circuit Valid RESET Logic State for Any Input Above 1V is designed to maintain system integrity in multi-supply 1% Accuracy for All Inputs systems. The device monitors its own power supply volt- Low 17A Supply Current age in addition to three other system supply voltages and Open-Drain RESET Output with 18A Internal Pullup asserts the reset output whenever any supply voltage falls Immune to Short Monitored Supply Transients below its reset threshold. After all of the supply voltages Internally Fixed/Adjustable Threshold Options rise above their reset thresholds, the reset output remains -40C to +125C Operating Temperature Range asserted for the reset timeout period, and then deasserts.

The open- drain output has a weak 18A (typ) pullup to IN2/V , CC eliminating the need for external pullup resistors. The MAX16160 offers a wide range of threshold options. Input thresholds may be fixed or adjustable. Fixed reset voltage thresholds for IN1, IN3, IN4 are available from 0.5V to 5V in approximately 20mV increments. Reset volt- age thresholds for IN2/V are available from 1.76V to 5V CC in approximately 20mV increments. The MAX16160 operates over the -40C to +125C tem- perature and is available in a small, 6-bump WLP and 6-pin SOT23 package.
