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 (VCC) level.
Tolerance level options are 5%, 10% and 20%.
When an out-oftolerance 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 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.
