ASM161 uP Supervisory Circuit

The ASM161 and ASM162 are cost effective, low power supervisory circuits that monitor power supplies in microprocessor, microcontroller and digital systems. If the power supply drops below the reset threshold level, a reset is asserted and remains asserted for at least 800 ms after VCC has risen abo.
