The TCM811 and TCM812 are cost-effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. A manual reset input is provided to override the reset monitor, and is suitable for use as a push-button reset. The TCM811 has an active-low RESET output while the TCM812 has an active-high RESET output. Both devices are available in industry standard pin-out and industry standard 4-Pin SOT-143 package. The TCM811/812 are optimized to reject fast transient glitches on the VCC line and are suitable for all battery powered applications.
