Power-Supply Voltage. Connect a 0.1µF bypass capacitor from V
Multiplier Input Voltage. Voltage input for internal multiplier.
Latch Enable for Comparator 1. Driving logic low makes the comparator
transparent (regular comparator). Driving logic high latches the output.
Open-Drain Comparator 1 Output. Output controlled by LE and INHIBIT.
INHIBIT for Comparator 1 Output. Driving logic high inhibits the comparator
operation. Drive logic low for normal operation.

Power Output Voltage. Voltage output proportional source power (input voltage
multiplied by load current).
Current Output Voltage. Voltage output proportional V
current.
