资源说明:The TCM811 and TCM812 are cost effective system supervisory circuits designed to monitor VDD 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. The reset output is driven active within 20 μs (5 μs for F version) of VDD falling through the reset voltage threshold. RESET is maintained active for a minimum of 140 ms after VDD rises above the reset threshold. 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 VDD = 1V. Both 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 VDD line. A low supply current of 6 μA (VDD = 3.3V) makes these device
