AS1925, Ultra-Low Voltage Microprocessor Supervisory Circuit

The AS1925/AS1926 microprocessor supervisory circuits were designed to assert a single reset if the monitored supply voltage drops below its reset threshold or if the manual reset is activated.

The reset remains asserted for a fixed timeout delay after VCC has risen above the reset threshold and the
