**STMicroelectronics** · Gate Drivers · SO-8

L6388ED from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LIN | input | Low-side driver logic input, TTL/CMOS compatible (3.3V, 5V, 15V) with internal hysteresis and pull-down |
| 2 | HIN | input | High-side driver logic input, TTL/CMOS compatible (3.3V, 5V, 15V) with internal hysteresis and pull-down |
| 3 | VCC | power_in | Low-voltage supply (max 17V), UV lock-out threshold at 9.6V turn-on and 8.3V turn-off |
| 4 | GND | power_in | Ground return and reference |
| 5 | LVG | output | Low-side driver output, 400mA source and 650mA sink current, maximum 0.3V low output voltage |
| 6 | OUT | power_in | Floating reference node (range -3V to 580V to GND) connected to external MOSFET source |
| 7 | HVG | output | High-side driver output floating from OUT to VBOOT, 400mA source and 650mA sink current |
| 8 | VBOOT | power_in | Bootstrap supply voltage, minimum 17V above OUT, maximum 618V absolute |

## CAD (KiCad official)

- Symbol: `L6388ED`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SO-8 (KiCad packages3D, STEP)
- 3D model files: `l6388ed-etched.step` / `l6388ed-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `l6388ed.step` / `l6388ed.glb` are the bare package body.
