Analog Devices / Maxim Integrated MAX1614x High Voltage Supervisors

Analog Devices MAX1614x High Voltage Supervisors monitor the circuit's supply voltages using a factory-set reset threshold that ranges from +2.3V to +11.6V. A manual reset (MR or MR) input is included. The RESET (or RESET) output has options for active-low, active-high, push-pull, or open-drain. The reset output asserts when the monitored voltage falls below the threshold voltage. This output remains asserted until the monitored voltage has exceeded its threshold (plus hysteresis) for a time equal to the factory-set reset timeout period. The available reset timeout periods for the Analog Devices MAX1614x range from 30μs to 4.2s.
