MAX16058ATA16+

The MAX16058ATA16+ is a 125nA supervisory circuit with capacitor adjustable reset and watchdog timeouts in 8 pin TDFN package. This ultra low current 125nA microprocessor (μP) supervisory circuit monitors a single system supply voltage. It asserts an active-low reset signal whenever VCC supply voltage drops below the factory trimmed reset threshold, manual reset is pulled low or the watchdog timer runs out. The reset output remains asserted for an adjustable reset timeout period after VCC rises above the reset threshold. This device features an adjustable reset and watchdog timeout using external capacitors. The MAX16058 contains a watchdog timer with a watchdog select input (WDS) that multiplies the watchdog timeout period by 128.
