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.
