FD2203S

Fortior Tech · Gate Drivers · SO-8

FD2203S from Fortior Tech, 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 VCC power_in Low-side supply voltage, recommended 8 V to 20 V referenced to COM, with absolute maximum -0.3 V to 25 V and UVLO trip at 6.3 V to 7.5 V.
2 HIN input High-side logic input (in phase with HO), with VIH minimum 2.4 V, VIL maximum 0.8 V, and a recommended range of 0 V to VCC.
3 LIN* input Low-side logic input (inverted at LO), with VIH minimum 2.4 V, VIL maximum 0.8 V, and a recommended range of 0 V to VCC.
4 COM power_in Ground reference for all pins; all voltage ratings in the datasheet are referenced to COM.
5 LO output Low-side gate drive output, swinging between 0 V and VCC, with low-level output short-circuit pulse current of 1.6 A minimum and 2.3 A typical (PWD ≤ 10 µs).
6 VS power_in High-side floating offset voltage, recommended -2 V to 250 V referenced to COM, with dVS/dt limited to 50 V/ns and static negative voltage of -6.0 V typical.
7 HO output High-side gate drive output, referenced to VS and swinging between VS and VB, with high-level output short-circuit pulse current of 1.1 A minimum and 1.6 A typical (PWD ≤ 10 µs).
8 VB power_in High-side floating supply voltage, recommended VS+8 V to VS+20 V, with absolute maximum of 275 V referenced to COM and UVLO trip at 6.3 V to 7.5 V.
