Pin
QFN36 TQFP48
Type Function
Analog GND. Tie to GND plane.
GNDA

32
Output of internal 5V regulator. Attach 2.2µF or larger
ceramic capacitor to GNDA near to pin for best
performance. May be used to supply VCC of chip.
5V supply input for digital circuitry within chip and
charge pump. Attach 470nF capacitor to GND (GND plane).
May 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.
Charge pump capacitor input. Tie to CPO using 22nF 50V
capacitor.
Charge pump voltage. Tie to VS using 100nF capacitor.
Analog supply voltage for 5V regulator. Normally tied to
VS. Provide a 100nF filtering capacitor.

Motor coil A output 2
Sense resistor connection for coil A. Place sense resistor
to GND near pin. An additional 100nF capacitor to GND
(GND plane) is recommended for best performance.
Motor coil A output 1
Test mode input. Tie to GND using short wire.
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 digital circuitry.
