Low Power, 5V P Reset
- Active LOW, Push-Pull Output
General Description
The ASM1810 is a voltage supervisor with low-power, 5V P
active LOW Reset, Push-Pull output. Maximum supply current
over temperature is a low 20A.
The ASM1810 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%, 10% and 15%. 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 150ms to allow the power supply and system
microprocessor to stabilize.
The ASM1810 is designed with a push-pull output stage and
operates over the extended industrial temperature range.
Devices are available in low cost TO-92 and compact surface
mount SOT-23 packages.
Other low power products in this family include the ASM1811/
12/15/16/17, ASM1233D and ASM1233M.
