Low Power, 3.3V/3.0V µP Reset Active LOW, Push-Pull Output

General Description

Applications

The ASM1815 is a voltage supervisory device with low-power,

3.3V/3.0V µP Reset, active LOW, Push-Pull output. Maximum

supply current over temperature is a low 15µA (at 3.6V).

The ASM1815 generates an active LOW reset signal whenever

the monitored supply is out of tolerance. A precision reference

and comparator circuit monitor power supply (V_CC

level.

Single board computers

Tolerance level options are 5%, 10% and 20%. When an out-of-

tolerance condition is detected, an internal power-fail signal is

generated which forces an active LOW reset signal. After V_CC

returns to an in-tolerance condition, the reset signal remains

active for 150ms to allow the power supply and system

microprocessor to stabilize.

ASM1815

The ASM1815 is designed with a push-pull output stage and

operates over the extended industrial temperature range.

Devices are available in TO-92 and compact surface mount

SOT-23 packages.
