AS1916 Microprocessor Supervisory Circuit

The AS1916 - AS1918 microprocessor supervisory circuits were designed to generate a reset when the monitored supply voltage falls below a factory-trimmed threshold. The reset remains asserted for a minimum timeout period after the supply voltage stabilizes. Guaranteed to be in the correct state for VCC higher than +1.0V, these devices are ideal for portable.
