IN4

Input Voltage 4. See Ordering Information on page 14 for monitored voltages.

GND

Ground

3

RESETN

Reset Output. AS1923A (see Ordering Information on page 14) supports an external pullup resistor; AS1923B

contains an internal 10µA current source pullup. RESETN goes low (reset asserted) when any one of the INx

voltages goes below its specified threshold. After all inputs have stabilized, RESETN remains low for at least

120ms (min) before going high.

IN1

Input Voltage 1. See Ordering Information on page 14 for monitored voltages.

IN2

Input Voltage 2. See Ordering Information on page 14 for monitored voltages.

Note:

IN2 is the power supply input for the AS1923.
