Functional Block Diagram. VISO Pin (Pin 14) Pin Functional Description This pin is the secondary-side positive supply voltage. VCC Pin (Pin 1) COM Pin (Pin 15) This pin is the primary-side supply voltage connection. This pin provides the secondary-side reference potential. GND Pin (Pin 3-6) GL Pin (Pin 16) This pin is the connection for the primary-side ground potential. This pin is the driver output-sinking current (turn-off) connection. All primary-side voltages refer to this pin. IN Pin (Pin 7) This pin is the input for the logic command signal. SO Pin (Pin 8) This pin is the output for the logic fault signal (open drain). NC Pins (Pin 9) This pin must be un-connected. Minimum PCB pad size for soldering is required. VEE Pin (Pin 10) Common (MOSFET source) output supply voltage. SNS Pin (Pin 11) This pin is the sense input detecting short-circuit events at turn-on and limiting overvoltages at turn-off. SiC MOSFET with sense function can be used with SNS pin as over-current monitor. VGXX Pin (Pin 12) This pin is the bootstrap and charge pump supply voltage source. Figure 4. Pin Configuration. GH Pin (Pin 13) This pin is the driver output-sourcing current (turn-on) connection. 2 Rev. B 11/19 www.power.com
