MAX6865UK42D2S+T

Supervisors Overview

The MAX6865UK42D2S+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.2 V. The device utilizes an SOT-23-5 surface-mount package and provides an active low, push-pull reset output with a minimum reset timeout of 40 ms. Designed for industrial environments, it supports an operating temperature range from -40°C to +85°C. The component is classified as obsolete.
