NAME FUNCTION
13V
CC
Power-Supply Voltage. Connect a 0.1µF bypass capacitor from V
CC
to GND.
2 4 IN Multiplier Input Voltage. Voltage input for internal multiplier.
35 LE
Latch Enable for Comparator 1. Driving logic low makes the comparator
transparent (regular comparator). Driving logic high latches the output.
4 6 COUT1 Open-Drain Comparator 1 Output. Output controlled by LE and INHIBIT.
5 7 INHIBIT
INHIBIT for Comparator 1 Output. Driving logic high inhibits the comparator
operation. Drive logic low for normal operation.
6 8 COUT2 Open-Drain Comparator 2 Output
7 9 GND Ground
8 10 CIN2+ Comparator 2 Positive Input
9 11 CIN2- Comparator 2 Negative Input
10 12 CIN1+ Comparator 1 Positive Input
11 13 CIN1- Comparator 1 Negative Input
12 14 REF 1.21V Internal Reference Output
13 15 POUT
Power Output Voltage. Voltage output proportional source power (input voltage
multiplied by load current).
14 16 IOUT
Current Output Voltage. Voltage output proportional V
