AS1923 supervisory equivalent, quad-voltage microprocessor supervisory.
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 in.
The device is ideal for portable and battery-powered systems, embedded controllers, intelligent instruments, automotive .
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 .
