IR11682STRPBF

Infineon Technologies · AC-DC Controllers And Regulators · SOIC-8

IR11682STRPBF from Infineon Technologies, 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 GATE1 output Gate drive output 1 is internally clamped (10.7 V typ.) with +1 A source / -4 A sink peak drive capability, and a gate resistor is recommended, especially when MOSFETs are paralleled.
2 VCC power_in Supply voltage pin monitored by the UVLO circuit, operating range 8.6 V to 18 V (absolute maximum 20 V), and it is not internally clamped.
3 VS1 input Differential source voltage sense for sync FET 1, which must be Kelvin-connected as close as possible to the MOSFET source pin and must not be tied directly to GND (pin 7).
4 VD1 input High-voltage drain voltage sense for sync FET 1, rated -3 V to 200 V recommended (-3 V spikes limited to 100 ns), with a 1 kΩ to 2 kΩ series resistor recommended when VD exceeds 100 V.
5 VD2 input High-voltage drain voltage sense for sync FET 2, rated -3 V to 200 V recommended (-3 V spikes limited to 100 ns), with a 1 kΩ to 2 kΩ series resistor recommended when VD exceeds 100 V.
6 VS2 input Differential source voltage sense for sync FET 2, which must be Kelvin-connected as close as possible to the MOSFET source pin and must not be tied directly to GND (pin 7).
7 GND power_in Analog and power ground; the internal circuitry and gate drivers are referenced to this pin, and output voltage and current parameters are referenced to it.
8 GATE2 output Gate drive output 2 is internally clamped (10.7 V typ.) with +1 A source / -4 A sink peak drive capability, and a gate resistor is recommended, especially when MOSFETs are paralleled.
