High-Voltage Supervisors with Manual Reset Input

High-Voltage Supervisors with Manual Reset Input


Please check latest availability status for a specific part variant.

Description

The MAX16143, MAX16145, MAX16147, and MAX16149 are supervisory circuits that monitor their own supply voltages using a factory-set reset threshold that ranges from +2.3V to +11.6V. A manual reset (MR or active-low MR) input is included. The RESET (or active-low 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, and remains asserted until the monitored voltage has exceeded its threshold (plus hysteresis) for a time equal to the factory-set reset timeout period. Available reset timeout periods range from 30µs to 4.2s.

The 5-pin SOT23 and 4-bump wafer-level packages (WLPs) offer compatibility with space-constrained environments. These ICs are fully specified over the -40°C to +125°C temperature range.
