TCM811/TCM812
4-Pin Reset Monitors
Features
General Description
• Precision VDD Monitor 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 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
• Manual Reset Input
• 140 ms Minimum RESET Output Duration
• RESET Output Valid to VDD = 1.0V (TCM811)
• Low 6 µA (typ.) Supply Current
• VDD Transient Immunity
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.
• 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 VDD line. A low supply current
of 6 µA (VDD = 3.3V) makes these devices ideal for
battery powered applications.

3.1
Ground Terminal (GND)
3.4
Manual Reset (MR)
GND provides the negative reference for the analog
input voltage. Typically, the circuit ground is used.
The Manual Reset (MR) input pin allows a push button
switch to easily be connected to the system. When the
push button is depressed, it forces a system Reset.
This pin has circuitry that filters noise that may be
present on the MR signal.
3.2
Reset Output (RESET) (TCM811)
RESET output remains low while VDD is below the
Reset voltage threshold (VTRIP). Once the device
voltage (VDD) returns to a high level (VTRIP + VHYS), the
device will remain in Reset for the Reset delay timer
(TRST). After that time expires, the RESET pin will be
driven to the high state.
The MR pin is active-low and has an internal pull-up
resistor.
3.5
Supply Voltage (VDD)
VDD can be used for power supply monitoring or a
voltage level that requires monitoring.
3.3
Reset Output (RESET) (TCM812)
RESET output remains high while VDD is below the
Reset voltage threshold (VTRIP). Once the device
voltage (VDD) returns to a high level (VTRIP + VHYS), the
device will remain in Reset for the Reset delay timer
(TRST). After that time expires, the RESET pin will be
driven to the low state.

such that it does not appreciably load RESET under
normal operation (100 kΩ will be suitable for most
applications). Similarly, a pull-up resistor to VDD is
required for the TCM812 to ensure a valid high RESET
for VDD below 1.1V.

APPLICATIONS INFORMATION
The TCM811/TCM812 provides accurate VDD
monitoring and reset timing during power-up, power-
down, and brownout/sag conditions. These devices
also reject negative-going transients (glitches) on the
power supply line. Figure 4-1 shows the maximum
transient duration vs. maximum negative excursion
(overdrive) for glitch rejection. Any combination of
duration and overdrive that is under the curve will not
generate a reset signal. Combinations above the curve
are detected as a brownout or power-down. Transient
immunity can be improved by adding a 0.1 µF capacitor
in close proximity to the VDD pin of the TCM811/
TCM812.

Controllers and Processors With
Bidirectional I/O Pins
320
240
160
Some microcontrollers have bidirectional reset pins.
Depending on the current drive capability of the
controller pin, an indeterminate logic level may result if
there is a logic conflict. This can be avoided by adding
a 4.7 kΩ resistor in series with the output of the
TCM811/TCM812 (Figure 4-3). If there are other
components in the system which require a reset signal,
they should be buffered so as not to load the reset line.
If the other components are required to follow the reset
I/O of the microcontroller, the buffer should be
connected as shown with the solid line.

The TCM811 RESET push-pull output is valid to
VDD = 1.0V. Below this voltage the output becomes an
"open circuit" and does not sink current. This means
CMOS logic inputs to the microcontroller will be floating
at an undetermined voltage. Most digital systems are
completely shutdown well above this voltage. How-
ever, in situations where RESET must be maintained
valid to VDD = 0V, a pull-down resistor must be con-
nected from RESET to ground to discharge stray
capacitances and hold the output low (Figure 4-2). This
resistor value, though not critical, should be chosen
