1 / 14 page 2002 Microchip Technology Inc. DS21615B-page 1 M TCM811/TCM812 Features • Precision V DD Monitor for 2.0V, 2.8V, 3.0V, 3.3V, 5.0V Nominal Supplies • Manual Reset Input • 140 msec Minimum RESET Output Duration • RESET Output Valid to V DD = 1.0V (TCM811) • Low 6 µA (typ.) Supply Current •V DD Transient Immunity • Small 4-Pin SOT-143 Package • No External Components • Replacement for MAX811/812 and Offers a Lower Threshold Voltage Option • Push-Pull RESET Output • Temperature Range: - Commercial (C) -40°C to +85°C Applications • Computers • Embedded Systems • Battery Powered Equipment • Critical Microcontroller Power Supply Monitoring Typical Application Circuit 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 control- ler 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 µsec (5 µsec for F version) of V DD falling through the reset voltage threshold. RESET is maintained active for a minimum of 140 msec after V DD rises above the reset threshold. The TCM812 has an active high RESET output while the TCM811 has an active low RESET output. The out- put of the TCM811 is valid down to V DD = 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 tran- sient glitches on the V DD line. A low supply current of 6µA (V DD = 3.3V) makes these devices ideal for battery powered applications.
