Description

1

Input Ground

2

Positive input supply voltage. (4.5 V to 5.5 V)

3

FAULT

Fault output. FAULT changes from a high impedance state

to a logic low output within 5 µs of the voltage on the

DESAT pin exceeding an internal reference voltage of 6.5 V.

FAULT output is an open collector which allows the FAULT

outputs from all ACPL-331J in a circuit to be connected

together in a “wired OR” forming a single fault bus for inter-

facing directly to the micro-controller.

14

DESAT

Desaturation voltage input. When the voltage on DESAT

exceeds an internal reference voltage of 6.5 V while the

IGBT is on, FAULT output is changed from a high impedance

state to a logic low state within 5 µs.

15

LED anode. This pin must be left unconnected for guaran-

teed data sheet performance. (For optical coupling testing

only)

16

Common (IGBT emitter) output supply voltage.
