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 voltage 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. ●
● During power-up, and before all of the input voltages exceed their trip thresholds, the reset output asserts low if
any of the monitored inputs is greater than 1V. The opendrain output has a weak 18μA (typ) pullup to IN2/VCC,
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 voltage thresholds for IN2/VCC are available from 1.76V to 5V
in approximately 20mV increments.
The MAX16160 operates over the -40°C to +125°C temperature and is available in a small, 6-bump WLP and …
