SI8261BBC-C-IS

SKYWORKS SILICON LABS · Gate Drivers · SOIC-8

SI8261BBC-C-IS from SKYWORKS SILICON LABS, in a SOIC-8. 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 NC unconnected No connect. Not internally connected. To maximize CMTI performance, this pin should be connected to the ground plane.
2 ANODE input Anode of LED emulator input. VO follows the signal applied to this input with respect to the CATHODE input. Input forward voltage (ON) 1.6 to 2.8 V; input current threshold typ 3.6 mA max; recommended IF(ON) 6-30 mA.
3 CATHODE input Cathode of LED emulator input. VO follows the signal applied to ANODE with respect to this input. Return for the input LED-emulator current path.
4 NC unconnected No connect. Not internally connected. To maximize CMTI performance, this pin should be connected to the ground plane.
5 GND power_in External MOSFET source connection and ground reference for VDD. Typically connected to ground but may be tied to a negative or positive voltage.
6 VO output Gate-driver output signal. Both VO pins (pins 6 and 7) MUST be shorted together for 4.0 A peak drive compliance. Rail-to-rail output; typical output resistance 2.6 Ω source / 0.8 Ω sink.
7 VO output Gate-driver output signal. Both VO pins (pins 6 and 7) MUST be shorted together for 4.0 A peak drive compliance. Rail-to-rail output; typical output resistance 2.6 Ω source / 0.8 Ω sink.
8 VDD power_in Output-side power supply input, referenced to GND. Operating range 6.5 to 30 V (30 V absolute max). Minimum 1 µF decoupling capacitor recommended from VDD to GND.
