FAN73901MX

onsemi · Gate Drivers · SOIC-8

FAN73901MX from onsemi, in a SOIC-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 HIN input Logic input for the high-side gate driver output, with logic "1" requiring at least 2.5 V and logic "0" at most 1.2 V and inputs rated from COM to VDD.
2 LIN input Logic input for the low-side gate driver output, with logic "1" requiring at least 2.5 V and logic "0" at most 1.2 V and inputs rated from COM to VDD.
3 COM power_in Low-side driver return and reference for the logic inputs and the LO output, with VLO and VIN specified relative to COM.
4 LO output Low-side driver output, specified from COM to VDD, capable of typically 2.5 A sourcing and sinking.
5 VDD power_in Low-side and logic supply, recommended at 10 V to 20 V, with the under-voltage lockout positive-going threshold typically 8.8 V.
6 VS power_in High-voltage floating supply return, with VS offset up to 600 V and slew rate limited to 50 V/ns maximum.
7 HO output High-side driver output, referenced to VS and specified between VS and VB.
8 VB power_in High-side floating supply, recommended at VS + 10 V to VS + 20 V, with the high-side driver operating up to VB = 625 V absolute maximum.
