Low Power, 5V µP Reset
- Active LOW, Push-Pull Output
General Description
Key Features
The ASM1810 is a voltage supervisor with low-power, 5V µP
active LOW Reset, Push-Pull output. Maximum supply current
over temperature is a low 20µA.

The ASM1810 generates an active LOW reset signal whenever
the monitored supply is out of tolerance. A precision reference
and comparator circuit monitor power supply (VCC) level.

Tolerance level options are 5%, 10% and 15%. When an out-of-
tolerance condition is detected, an internal power-fail signal is
generated which forces an active LOW reset signal. After VCC

Application Information
Operation - Power Monitor
tR
The ASM1810 detects out-of-tolerance power supply
conditions. It resets a processor during power-up, power-down
and issues a reset to the system processor when the monitored
power supply voltage is below the reset threshold. When an
out-of-tolerance VCC voltage is detected, the RESET signal is
VCCTP (MAX)
VCCTP
VCCTP (MIN)
asserted. On power-up, RESET is kept active (LOW) for
approximately 150ms after the power supply voltage has
reached the selected tolerance. This allows the power supply
and microprocessor to stabilize before RESET is released.

Output Conditions
The ASM1810 active LOW reset signal is valid as long as VCC
remains above 1.2V. However the RESET output on the
ASM1810 uses a push-pull drive stage that can maintain a valid
output below 1.2V. To sink current with VCC below 1.2V, a
t
RESET
RPD
resistor can be connected from the reset pin (RESET) to
Ground (see Figure 1). This configuration will give a valid value
on the RESET output with VCC approaching 0V. During both
power up and down, this configuration will draw current when
the RESET is in the high state. A value of 100kΩ should be
adequate to maintain a valid connection.
