The ASM1233D-L/1233D/1233M is a low-power, 5V/3.3V microprocessor reset circuit with an active LOW, open-drain output. It generates an active LOW reset signal when the monitored supply voltage is out of tolerance and keeps the reset signal active for 350ms after the supply voltage returns to normal to stabilize the system. This product features low supply current, automatic microprocessor restart, etc.
The ASM1233D-L, ASM1233D, and ASM1233M are voltage supervisors designed to generate an active LOW reset signal whenever the monitored supply is out of tolerance. These devices utilize a precision reference and comparator circuit to monitor power supply levels with 5%, 10%, or 15% tolerances.
