MAX16160
High-Accuracy 4-Channel, Any-Input
Supervisory Circuits
General Description
Benefits and Features
The MAX16160 precision, four-channel supervisory circuit
is designed to maintain system integrity in multi-supply
systems.The device monitors its own power supply volt-
age in addition to three other system supply voltages and
asserts the reset output whenever any supply voltage falls
below its reset threshold. After all of the supply voltages
rise above their reset thresholds, the reset output remains
asserted for the reset timeout period, and then de-asserts.
● Valid RESET Logic State for Any Input Above 1V
● ±1% Accuracy for All Inputs
● Low 17µA Supply Current
● Open-Drain RESET Output with 18μA Internal Pullup
● Immune to Short Monitored Supply Transients
● Internally Fixed/Adjustable Threshold Options
● -40°C to +125°C Operating Temperature Range
● Small, 6-Pin SOT23 Package and 6-Bump WLP
During power-up, and before all of the input voltages ex-
ceed their trip thresholds, the reset output asserts low if
any of the monitored inputs is greater than 1V. The open-
Ordering Information appears at end of data sheet.
drain output has a weak 18μA (typ) pullup to IN2/V
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 -40°C to +125°C tem-
perature and is available in a small, 6-bump WLP and
6-pin SOT23 package.
