Pin description (continued)
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 56kΩ resistor are internally connected between this pin
and GND1 (Pin13), giving a 16 µs -time.
Logic stage GND. Return path for the logic signals and VSS (pin1) supply
voltage.
Power stage GND. Return path for the power stage and VS (pin19) supply
voltage.
Phase D output
Phase C output
Phase B output
Phase A output
Power stage supply voltage. Module and motor supply voltage.
Maximum voltage must not exceed the specified values.
