MAX16162NGK190+T

Supervisors Overview

The MAX16162NGK190+T is a low-power, glitch-free supervisor IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors input voltage and asserts a reset signal when the supply drops below a specific threshold. The device features an ultra-low quiescent current of 825nA typical, extending battery life in portable applications. It offers multiple reset timeout options and supports threshold voltages ranging from 0.6V to 4.85V. The component is available in a compact 4-pin SOT-23 package and operates within a temperature range of -40°C to +125°C.
