General Description
The TCM811 and TCM812 are cost effective system
supervisory circuits designed to monitor V
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.
The reset output is driven active within 20 µs (5 µs for
F version) of V
threshold. RESET is maintained active for a minimum
of 140 ms after V
The TCM812 has an active high RESET output while
the TCM811 has an active low RESET output. The
output of the TCM811 is valid down to V
devices are available in a 4-Pin SOT-143 package,
specified with a temperature range of -40°C to +85°C.
The TCM811/TCM812 are optimized to reject fast
transient glitches on the V
of 6 µA (V
