AS1911 Dual-Voltage Microprocessor Supervisory Circuits

The AS1910 - AS1915 microprocessor supervisory circuits were designed to generate a reset when one of the two monitored supply voltages falls below a factorytrimmed threshold, and to maintain the reset for a minimum timeout period when both supplies are above their reset thresholds. Guaranteed to be in the correct state for VCC higher than +1.0V, these devic.
