125nA Supervisory Circuits with CapacitorAdjustable Reset and Watchdog Timeouts
General Description
The MAX16056­MAX16059 are ultra-low-current 125nA (typ) microprocessor (µP) supervisory circuits that monitor a single system supply voltage.

These devices assert an active-low reset signal whenever the V CC supply voltage drops below the factory-trimmed reset threshold, manual reset is pulled low, or the watchdog timer runs out (MAX16056/MAX16058). The reset output remains asserted for an adjustable reset timeout period after V CC rises above the reset threshold. Factorytrimmed reset threshold voltages are offered from 1.575V to 4.625V in approximately 100mV increments (see Table 1). These devices feature adjustable reset and watchdog timeout using external capacitors. The MAX16056/ MAX16058 contain a watchdog timer with a watchdog select input (WDS) that multiplies the watchdog timeout period by 128. The MAX16057/MAX16059 do not have the watchdog feature.
