RCB

Phase C/D current controller -Time set pin.

Use this pin to set the desired Off-time of the switching current controller.

A 470pF capacitor and 56k

Ω resistor are internally connected between this pin

and GND1 (Pin13), giving a 16 µs -time.

GND1

Logic stage GND. Return path for the logic signals and VSS (pin1) supply

voltage.

14

GND2

Power stage GND. Return path for the power stage and VS (pin19) supply

voltage.

15

PHD

Phase D output

16

PHC

Phase C output

17

PHB

Phase B output

18

PHA

Phase A output

19

VS

Power stage supply voltage. Module and motor supply voltage.

Maximum voltage must not exceed the specified values.
