Low Power, 5V/3.0V, µP Reset, Active LOW, Open-Drain Output

October 2003

General Description

The ASM1233M is a voltage supervisor with low-power, 5V µP

Reset, with an active LOW, open-drain output. Maximum supply

current over temperature is a low 20µA.

The ASM1233M 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% ,and 10% for a 5V power

supply. The tolerance is 15% for the 3.3V, ASM1233M. When

an out-of-tolerance condition is detected, an internal power-fail

signal is generated which forces an active LOW reset signal.

After VCC returns to an in-tolerance condition, the reset signal

remains active for 350ms to allow the power supply and system

microprocessor to stabilize.

The ASM1233M is designed with a open-drain output stage and

operates over the extended industrial temperature range.

Devices are available in compact surface mount SO-8

packages and 3-lead TO-92 packages.

Other low power products in this family include the ASM1810/

11/12/15/16/17 and ASM1233D.
