ACPL-332J

AOTE · Gate Drive Optocoupler · SOP-16

ACPL-332J from AOTE, in a SOP-16. 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 reference for the primary (LED input) side.
2 VCC1 power_in Positive input supply voltage, 3.3V to 5.5V range (7V absolute max).
3 FAULT output Open-collector fault output. Transitions from high-impedance to logic low within 5us when DESAT exceeds the internal 7V reference. Multiple FAULT pins can be wire-OR connected onto a single fault bus to a microcontroller. Max FAULT current 8mA; VFAULT range -0.5V to VCC1.
4 VS power_in Input ground reference for the primary (LED input) side.
5 CATHODE input LED cathode of the primary input optocoupler channel. Drive with 7-16mA forward current for the ON state.
6 ANODE input LED anode of the primary input optocoupler channel. Reverse voltage max 5V; average input current max 25mA.
7 ANODE input LED anode of the primary input optocoupler channel (paired with pin 8 cathode).
8 CATHODE input LED cathode of the primary input optocoupler channel (paired with pin 7 anode).
9 VEE power_in Negative output supply voltage rail. Total (VCC2-VEE) rated 15-30V operating (35V abs max).
10 VCLAMP output Miller clamp output. Active clamp to VEE during off-state to prevent parasitic Miller-induced turn-on of the IGBT. Peak clamping sink current 1.7A.
11 VOUT output Gate drive voltage output. Sources/sinks up to 2.5A peak to drive the IGBT gate. Output swings between VCC2 and VEE.
12 VEE power_in Negative output supply voltage rail (tied to pin 9).
13 VCC2 power_in Positive output supply voltage. Rated 15-30V above VE; total (VCC2-VEE) 35V absolute max.
14 DESAT input Desaturation voltage input. Senses IGBT collector voltage while on; when it exceeds the internal 6.5V reference, FAULT transitions from high-impedance to logic low within 5us. Voltage range VE to VE+10V.
15 VLED unconnected LED anode used only for optical coupling factory test. Must be left unconnected in application for guaranteed datasheet performance.
16 VE power_in Common IGBT emitter reference. Output supply return; (VCC2-VE) rated 15V to 30V operating (30V abs max).
