AS1920 Datasheet (austriamicrosystems AG) - Triple-Voltage Micro-Power Microprocessor Supervisory Circuits

AS1920, Triple-Voltage Micro-Power Microprocessor Supervisory Circuits

The AS1920 and AS1922 microprocessor supervisory circuits were designed to generate a reset when at least one of the three monitored supply voltages falls below its respective trip threshold.

These very-low-current (6.2µA, typ) devices maintain reset for a minimum timeout period after all supplies h
