TCM811/TCM812

4-Pin Reset Monitors

Features

General Description

• Precision V_DDMonitor for 2.0V, 2.8V, 3.0V, 3.3V,

5.0V Nominal Supplies

The TCM811 and TCM812 are cost effective system

supervisory circuits designed to monitor V_DDin 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

• Manual Reset Input

• 140 ms Minimum RESET Output Duration

• RESET Output Valid to V_DD= 1.0V (TCM811)

• Low 6 µA (typ.) Supply Current

• V_DDTransient Immunity

for use as

push-button reset. No external

components are required.

The reset output is driven active within 20 µs (5 µs for

F version) of V_DDfalling through the reset voltage

threshold. RESET is maintained active for a minimum

of 140 ms after V_DDrises 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 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.

• 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

The TCM811/TCM812 are optimized to reject fast

transient glitches on the V_DDline. A low supply current

of 6 µA (V_DD= 3.3V) makes these devices ideal for

battery powered applications.
