Function
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.
