SL21814 from Slkor SLKORMICRO Elec, in a SOP-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 the high-side gate driver output HO, in phase with HO; Schmitt-triggered with pull-down, VIH min 2.5 V and VIL max 0.8 V, compatible with 3.3 V and 5 V logic.
2 LIN input Logic input for the low-side gate driver output LO, in phase with LO; Schmitt-triggered with pull-down, VIH min 2.5 V and VIL max 0.8 V, compatible with 3.3 V and 5 V logic.
3 VSS power_in Logic ground for the HIN and LIN inputs; absolute maximum range -5 V to +5 V.
4 NC unconnected No connection.
5 COM power_in Low-side return; all absolute and recommended voltage ratings are referenced to COM.
6 LO output Low-side gate drive output, swinging between 0 V and VCC and in phase with LIN.
7 VCC power_in Low-side and logic fixed supply; recommended 10 V to 20 V, absolute maximum -0.3 V to 25 V referenced to COM.
8 NC unconnected No connection.
9 NC unconnected No connection.
10 NC unconnected No connection.
11 VS power_in High-side floating supply return; offset up to 600 V with dV/dt limited to 50 V/ns, absolute range VB-25 V to VB+0.3 V.
12 HO output High-side gate drive output, swinging between VS and VB and in phase with HIN.
13 VB power_in High-side floating supply; recommended VS+10 V to VS+20 V, absolute maximum 625 V referenced to COM.
14 NC unconnected No connection.
