MAX16056ATA17+T

The MAX16056ATA17+T is a supervisory circuit with capacitor adjustable reset and watchdog timeouts in 8 pin TDFN package. This microprocessor (μP) supervisory circuit has ultra low supply current of 125nA and monitors single system supply voltage. This device asserts an active-low reset signal whenever the VCC supply voltage drops below the factory trimmed reset threshold, manual reset is pulled low or watchdog timer runs out. The reset output remains asserted for an adjustable reset timeout period after VCC rises above the reset threshold. The MAX16056 has adjustable reset and watchdog timeout using external capacitors. It contains a watchdog timer with watchdog select input (WDS) that multiplies watchdog timeout period by 128. The device is typically used in battery powered equipment.

• Supply voltage range from 1.1V to 5.5V at TA = 0°C to +125°C and 1.2V and 5.5V at TA = -40°C to 0°C
