Overview
ASM1233D, ASM1233D-L, ASM1233M Low Power, 5 V/3.
3 V, mP Reset, Active LOW, Open-Drain Output Description The ASM1233D−L/1233D/1233M are voltage supervisors with low−power, 5/3.
3 V mP Reset, with an active LOW, open−drain output.
Maximum supply current over temperature is 15 mA for 3.
3 V devices and 20 mA for 5 V devices.
The ASM1233D−L/1233D/1233M generates an active LOW reset signal whenever the monitored supply is out of tolerance.
A precision reference and comparator circuit monitors power supply (VCC) level.
The tolerances 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 350 ms to allow the power supply and system microprocessor to stabilize.
The ASM1233D−L/1233D/1233M is designed with an open drain output stage and operates over the extended industrial temperature range.
These devices are available in compact SOT−223, SO−8 and TO−92 packages.
Other low power products in this family include ASM1810/11/12/ 15/16/17.
