IR21814STRPBF from Infineon Technologies, in a SOIC-14. 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 HIN input Logic input for high side gate driver output (HO), in phase; 3.3V/5V logic compatible, referenced to VSS, internally clamped with a 5.2V zener.
2 LIN input Logic input for low side gate driver output (LO), in phase; 3.3V/5V logic compatible, referenced to VSS, internally clamped with a 5.2V zener.
3 VSS power_in Logic ground (IR21814 only), allowed -5V to +5V offset relative to COM.
4 NC unconnected Pin shown on the 14-lead SOIC drawing with no function label; the datasheet gives no signal for it.
5 COM power_in Low side return.
6 LO output Low side gate drive output, 1.4A source / 1.8A sink minimum pulsed current capability.
7 VCC power_in Low side and logic fixed supply, recommended 10V to 20V (absolute max 25V).
8 NC unconnected Pin shown on the 14-lead SOIC drawing with no function label; the datasheet gives no signal for it.
9 NC unconnected Pin shown on the 14-lead SOIC drawing with no function label; the datasheet gives no signal for it.
10 NC unconnected Pin shown on the 14-lead SOIC drawing with no function label; the datasheet gives no signal for it.
11 VS power_in High side floating supply return; offset operational to +600V (absolute max VB + 0.3V).
12 HO output High side gate drive output, 1.4A source / 1.8A sink minimum pulsed current capability.
13 VB power_in High side floating supply, VS + 10V to VS + 20V recommended (absolute max 625V).
14 NC unconnected Pin shown on the 14-lead SOIC drawing with no function label; the datasheet gives no signal for it.
