Type
Function
5VOUT
33
Output of internal 5V regulator. Attach 2.2µF or larger ceramic
capacitor to GNDA near to pin for best performance. Output to
supply VCC of chip.
VCC
34
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!
CPO
35
Charge pump capacitor output.
CPI
37
Charge pump capacitor input. Tie to CPO using 22nF 50V
capacitor.
VCP
38
Charge pump voltage. Tie to VS using 100nF capacitor.
VSA
39
Analog supply voltage for 5V regulator. Normally tied to VS.
Provide a 100nF filtering capacitor.
OA2
42
Motor coil A output 2
BRA
44
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.
OA1
46
Motor coil A output 1
Exposed die
pad
-
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.
*(pu) denominates a pin with pullup resistor; (tpu) denominates a pin with pullup resistor or toggle
detection. Toggle detection is active in standalone mode, only (SPI_MODE=0)
