DGD05473FNQ-7

Diodes Incorporated · Gate Drive ICs · DFN-10-EP(3x3)

DGD05473FNQ-7 from Diodes Incorporated, in a DFN-10-EP(3x3). 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 and logic supply, with a recommended operating range of 4.7V to 14V and an absolute maximum of +14V.
2 NC unconnected No internal connection; the datasheet lists this pin as no connection.
3 VB power_in High-side floating supply, with VB rated -0.3V to +60V absolute maximum and operating at VS + 4.4V to VS + 14V.
4 HO output High-side gate drive output, in phase with HIN and cross-conduction protected against LO.
5 VS power_in High-side floating supply return, with logic operation specified for VS from -5V to +50V.
6 EN input Logic input enable; a logic low turns off the gate driver, with a logic 1 threshold of 1.6V minimum.
7 HIN input Logic input for the high-side gate driver, in phase with HO, with logic 1 input voltage of 2.4V minimum.
8 LIN input Logic input for the low-side gate driver, in phase with LO, with logic 1 input voltage of 2.4V minimum.
9 COM power_in Low-side and logic return, serving as the ground reference for the device.
10 LO output Low-side gate drive output, with source current of 1.5A and sink current of 2.5A capability.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
