Pin
TQFP Type Function
5V supply input for digital circuitry within chip. Provide 100nF
or bigger capacitor to GND (GND plane) near pin. Shall be
supplied by 5VOUT. A 2.2 or 3.3 Ohm resistor is recommended
for decoupling noise from 5VOUT. When using an external
supply, make sure, that VCC comes up before or in parallel to
5VOUT or VCC_IO, whichever comes up later!
Charge pump capacitor output.

Connect the exposed die pad to a GND plane. Provide as many
as possible vias for heat transfer to GND plane. Serves as GND
pin for the low side gate drivers. Ensure low loop inductivity
to sense resistor GND.
