ASM1816/D

ASM1816

Low Power, 3.3 V/3.0 V,

mP Reset, Active LOW,

Open-Drain Output

Description

The ASM1816 is a voltage supervisory device with low−power,

3.3 V/3 V

mP Reset, active LOW, open−drain output. Maximum

supply current over temperature is a low 15

mA (at 3.6 V).

The ASM1816 generates an active LOW reset signal whenever the

monitored supply is out of tolerance. A precision reference and

options are 5%, 10%, 15% and 20%. When an out−of−tolerance

condition is detected, an internal power−fail signal is generated which

in−tolerance condition, the reset signal remains active for 150 ms to

allow the power supply and system microprocessor to stabilize.

The ASM1816 is designed with a open−drain output stage and

operates over the extended industrial temperature range. Devices are

available in TO−92 and compact surface mount SOT−23 packages.

Other low power products in this family include the

ASM1810/11/12/15/17, ASM1233D and ASM1233M.
