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 | VIN+ | input | Noninverting gate drive voltage output (VOUT) control input. TTL/CMOS compatible logic input referenced to GND1; VIH >= 2.0 V, VIL <= 0.8 V. |+| 2 | VIN- | input | Inverting gate drive voltage output (VOUT) control input. TTL/CMOS compatible logic input referenced to GND1; VIH >= 2.0 V, VIL <= 0.8 V. |+| 3 | VCC1 | power_in | Positive input-side supply voltage (4.5 V to 5.5 V). Powers the input logic and LED driver referenced to GND1. |+| 4 | GND1 | power_in | Input-side ground reference for VCC1, VIN+, VIN-, RESET and FAULT. |+| 5 | RESET | input | FAULT reset input (active low). A logic-low pulse of at least 0.1 us asynchronously resets the FAULT output high and re-enables VIN. RESET is not affected by UVLO; asserting RESET while VOUT is high does not affect VOUT. |+| 6 | FAULT | output | Open-collector FAULT output (active low). Transitions from high-impedance to logic low within 5 us when the DESAT pin voltage exceeds the internal 7 V reference. Remains low until RESET is asserted; can be wire-OR'd across multiple AT316J devices to form a single fault bus. |+| 7 | VLED1+ | passive | Internal LED1 anode test point. Must be left unconnected for guaranteed datasheet performance (for optical coupling factory testing only). |+| 8 | VLED1- | passive | Internal LED1 cathode. This pin must be connected to input ground (GND1). |+| 9 | VEE | power_in | Negative output-side supply voltage (output IC ground/return). Sets the low-side gate drive rail for the IGBT off-state. |+| 10 | VEE | power_in | Negative output-side supply voltage (output IC ground/return). Tied internally with pin 9; both pins should be connected together externally. |+| 11 | VOUT | output | Gate drive voltage output to the IGBT/MOSFET gate. Provides up to +/-2.5 A peak output current; swings between VCC2 (high) and VEE (low). |+| 12 | VC | power_in | Positive output-side supply voltage input to the driver collector stage. Range VEE+6 V to VCC2 per recommended operating conditions. |+| 13 | VCC2 | power_in | Positive output supply voltage. Total output supply (VCC2 - VEE) of 15 V to 30 V; feeds the high-side gate driver and UVLO monitor. |+| 14 | DESAT | input | Desaturation (VCE) voltage sense input. When the voltage on DESAT exceeds the internal 7 V reference while the IGBT is commanded on, FAULT changes from high impedance to logic low within 5 us, indicating IGBT desaturation/overcurrent. |+| 15 | VLED2+ | passive | Internal LED2 anode test point. Must be left unconnected for guaranteed datasheet performance (for optical coupling factory testing only). |+| 16 | VE | power_in | Common (IGBT emitter) output-side supply voltage reference. The output-side ground/emitter reference used by DESAT, VC and gate return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | AOTE |+| Package | SOP-16 |+| Category | Optoisolators |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `AT316J-CuH-S`++## CAD (KiCad official)++- Symbol: `AT316J-CuH-S`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [AOTE datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590916737233727488) (42 pp, sha256 `665d8c76ddb17ebe`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
