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 voltages have
stabilized. The output is valid as long as the IN1 or IN2 input voltage
remains >1V.
Key Features
■ Simultaneous Quad-Voltage Monitoring
■ Precision Factory-Trimmed Reset Threshold Options: +5.0, +3.3, +3.0, +2.5,
+1.8, and -5.0V
■ User-Adjustable Voltage Monitoring Threshold Options
■ Low Supply Current: 55µA
■ Open-Drain – AS1923A
■ 10µA Current Source Pullup – AS1923B
■ Reset Timeout Period: 120ms
■ RESET Valid to IN1 = 1V or IN2 = 1V
■ Immune to Fast INx Transients
■ External Components not Required
■ Guaranteed Performance: Operating Temperature Range = -40 to +85ºC
■ 6-pin SOT23 package
Applications
The device is ideal for portable and battery-powered systems, embedded controllers, intelligent instruments, automotive systems, critical CPU monitoring, and any multi-supply application.
