Floating bootstrap supply pin for high side gate driver. Connect the bootstrap capacitor between this pin
and the SW pin.
Control input. The PWM signal has three distinctive states: Low = Low Side FET Enabled, Mid = Diode
Emulation Enabled, High = High Side FET Enabled.
Logic input. A logic high to enable the part and a logic low to disable the part.
Power supply input. Connect a bypass capacitor (0.1 mF) from this pin to ground.
Low side gate drive output. Connect to the gate of low side MOSFET.
Bias and reference ground. All signals are referenced to this node (QFN Flag).
Switch node. Connect this pin to the source of the high side MOSFET and drain of the low side MOSFET.
Thermal flag. There is no electrical connection to the IC. Connect to ground plane.
High side gate drive output. Connect to the gate of high side MOSFET.
