TERMINAL FUNCTIONS

NO.

NAME

DESCRIPTION

1

PWM

Pulse-width modulation input. If not used, connect to I.

2

ST

Status output. Open-collector output. Connect to an external pullup resistor (RPULLUP ≥ 4.7 kΩ).

3

GND

Ground

4

REF

Reference input. Connect to a shunt resistor.

5

D

Status delay. To set status reaction delay, connect to GND with a capacitor. If no delay is needed, leave open.

6

Q

Output

7

NC

No internal connection

8

I

Input. Connect directly to GND as close as possible to the device with a 100-nF ceramic capacitor.
