Overview

com AS1923 Q u a d - Vo l ta g e M i c r o p r o c e s s o r S u p e r v i s o r y C i r c u i t Product Brief 1 General Description The AS1923 microprocessor supervisory circuit was designed to monitor up to four system supply voltages without the need for external components, and asserts a single reset if any of the monitored supply voltages drops below its reset threshold.
The AS1923 features an active-low reset output that is asserted when any of the 4 monitored voltages are below their respective reset threshold.
The reset output is open-drain with a weak internal pullup (10µA) to IN2.
Reset remains low for a specified reset timeout period (120ms min) after all voltag...
