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. |
