TCM811LE Datasheet - Microchip Technology

General Description
The TCM811 and TCM812 are cost effective system supervisory circuits designed to monitor V DD in digital systems and provide a reset signal to the host controller when necessary. A manual reset input is provided to override the reset monitor and is suitable for use as a push-button reset. No external components are required.
