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
comparator circuit monitor power supply (V_CC) level. Tolerance level
options are 5%, 10%, 15% 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 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.
