ACPL-331J-500E

Broadcom AVAGO · Logic Output Optoisolators · SOIC-16-300mil

ACPL-331J-500E from Broadcom AVAGO, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VS power_in Input ground return.
2 VCC1 power_in Positive input supply voltage, 3.3 V to 5.5 V.
3 FAULT tri_state Open collector fault output that goes low within 5 µs when DESAT voltage exceeds 6.5 V threshold.
4 VS power_in Input ground return.
5 CATHODE passive LED cathode terminal for input optical path.
6 ANODE passive LED anode terminal for input optical path.
7 ANODE passive LED anode terminal for input optical path.
8 CATHODE passive LED cathode terminal for input optical path.
9 VEE power_in Output supply voltage ground return.
10 VCLAMP output Miller clamp output with 2.0 V threshold for active gate voltage clamping during IGBT turn-off; short to VEE if not used.
11 VOUT output Gate drive voltage output providing up to 1.5 A peak output current to IGBT gate.
12 VEE power_in Output supply voltage ground return.
13 VCC2 power_in Positive output supply voltage, 15 V to 30 V operating range.
14 DESAT input IGBT collector-emitter voltage sense input; when voltage exceeds internal 6.5 V threshold while IGBT is on, FAULT output goes low within 5 µs.
15 VLED unconnected LED anode test point for optical coupling verification; must be left unconnected for guaranteed datasheet performance.
16 VE power_in Common IGBT emitter output supply voltage ground reference.
