L6398DTR 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, active low; the datasheet gives VIL of 0.8 V (min) to 1.1 V and VIH of 1.9 V to 2.25 V, with CMOS/TTL compatibility down to 3.3 V. |
| 2 | HIN | input | High-side driver logic input, active high; the datasheet gives VIL of 0.8 V (min) to 1.1 V and VIH of 1.9 V to 2.25 V, with CMOS/TTL compatibility down to 3.3 V. |
| 3 | VCC | power_in | Lower section supply voltage, recommended operating range 10 V to 20 V with an absolute maximum of 21 V. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | LVG | output | Low-side driver output; the circuit guarantees less than 1 V on LVG at Isink = 10 mA with VCC > 3 V, so an external gate-to-source bleeder resistor can be omitted. |
| 6 | OUT | power_in | High-side (floating) common voltage, recommended range up to 580 V with an absolute range of VBOOT - 21 V to VBOOT + 0.3 V. |
| 7 | HVG | output | High-side driver output referenced to OUT; the circuit guarantees less than 1 V on HVG at Isink = 10 mA with VCC > 3 V, so an external gate-to-source bleeder resistor can be omitted. |
| 8 | BOOT | power_in | Bootstrapped supply voltage for the high-side section, recommended floating supply 9.8 V to 20 V, with an absolute maximum VBOOT of 620 V. |
