FAN73896MX

onsemi · Gate Drive ICs · SOIC-28-300mil

FAN73896MX from onsemi, in a SOIC-28-300mil. 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 VDD power_in Logic and low-side gate driver power supply voltage, recommended 12 V to 20 V.
2 HIN1 input Logic input 1 for the high-side gate 1 driver, 3.3 V and 5.0 V logic compatible.
3 HIN2 input Logic input 2 for the high-side gate 2 driver, 3.3 V and 5.0 V logic compatible.
4 HIN3 input Logic input 3 for the high-side gate 3 driver, 3.3 V and 5.0 V logic compatible.
5 LIN1 input Logic input 1 for the low-side gate 1 driver, 3.3 V and 5.0 V logic compatible.
6 LIN2 input Logic input 2 for the low-side gate 2 driver, 3.3 V and 5.0 V logic compatible.
7 LIN3 input Logic input 3 for the low-side gate 3 driver, 3.3 V and 5.0 V logic compatible.
8 FO output Fault output with open drain that indicates over-current and low-side under-voltage shutdown.
9 CS input Analog input for over-current shutdown, with a 500 mV positive-going threshold.
10 EN input Logic input for shutdown functionality, where LOW shuts down the gate driver outputs.
11 RCIN passive External RC network input used to define the fault-clear delay.
12 VSS power_in Logic ground.
13 COM power_in Low-side driver return.
14 LO3 output Low-side gate driver 3 output.
15 LO2 output Low-side gate driver 2 output.
16 LO1 output Low-side gate driver 1 output.
17 NC unconnected No connect.
18 VS3 passive High-side driver 3 floating supply offset voltage, with VS allowed to swing from -9.8 V (typical) for VBS = 15 V.
19 HO3 output High-side driver 3 gate driver output.
20 VB3 power_in High-side driver 3 floating supply, rated up to +600 V.
21 NC unconnected No connect.
22 VS2 passive High-side driver 2 floating supply offset voltage, with VS allowed to swing from -9.8 V (typical) for VBS = 15 V.
23 HO2 output High-side driver 2 gate driver output.
24 VB2 power_in High-side driver 2 floating supply, rated up to +600 V.
25 NC unconnected No connect.
26 VS1 passive High-side driver 1 floating supply offset voltage, with VS allowed to swing from -9.8 V (typical) for VBS = 15 V.
27 HO1 output High-side driver 1 gate driver output.
28 VB1 power_in High-side driver 1 floating supply, rated up to +600 V.
