General Description

Single board computers

The ASM8500 is a voltage supervisory device with a low-power,

^5V/3.3V µP Reset, active LOW, open-drain output. Maximum

supply current over temperature is a low 6µA.

Typical Operating Circuit

The ASM8500 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. Reset

V_CC

threshold tolerance level is ±1.5%. When an out-of-tolerance

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

which forces an active LOW reset signal. After V_CCreturns to

GND

an in-tolerance condition, the reset signal remains active for

1.5ms to allow the power supply and system microprocessor to

stabilize.

RESET

The ASM8500 is designed with a open-drain output stage and

operates over the extended industrial temperature range.

Devices are available in compact surface mount SOT-89

packages.
