FAN7383MX from onsemi, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Gate driver logic input. Schmitt-trigger input; high-side output is in phase with IN. |
| 2 | SD | input | Shutdown logic input, active low. Pulling SD low disables both high-side and low-side outputs. |
| 3 | DT | input | Dead-time programming pin. An external resistor to GND sets the programmable dead time between HO and LO transitions (minimum ~330 ns). |
| 4 | VDD | power_in | Low-side and logic supply voltage input. Typically 15 V; UVLO monitors this rail. |
| 5 | LO1 | output | Low-side driver source-current output (sourcing leg, ~350 mA typical). Connect to the gate of the low-side MOSFET/IGBT, typically through a series turn-on resistor. |
| 6 | LO2 | output | Low-side driver sink-current output (sinking leg, ~650 mA typical). Connect to the gate of the low-side MOSFET/IGBT, typically through a series turn-off path/diode. |
| 7 | GND | power_in | Low-side ground reference for VDD, logic, and low-side driver. |
| 8 | NC | unconnected | No connection. Leave floating or tie for creepage between low-side and high-side domains. |
| 9 | NC | unconnected | No connection. Provides isolation spacing between low-side and high-side pins. |
| 10 | NC | unconnected | No connection. Provides isolation spacing between low-side and high-side pins. |
| 11 | VS | power_in | High-side floating supply return (switch-node reference). Connects to the source of the high-side MOSFET/IGBT; tolerates VS down to about -9.8 V (typ) with VDD = VBS = 15 V. |
| 12 | HO2 | output | High-side driver sink-current output (sinking leg, ~650 mA typical), referenced to VS. Connect to the gate of the high-side MOSFET/IGBT for turn-off. |
| 13 | HO1 | output | High-side driver source-current output (sourcing leg, ~350 mA typical), referenced to VS. Connect to the gate of the high-side MOSFET/IGBT for turn-on. |
| 14 | VB | power_in | High-side floating supply (bootstrap rail). Bypass to VS with the bootstrap capacitor; charged from VDD via the bootstrap diode/resistor. |
