Low Power, 3.3V/3.0V μP Reset Active LOW, Push-Pull Output
February 2005
General Description
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.
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.
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.
Other low power products in this family include the ASM1810/
11/12/16/17, ASM1233D and ASM1233M.
