Connect capacitor for charge pump (storage
side) V
Connect capacitor for charge pump (charging
side) between this pin and Ccp C.
Connect capacitor for charge pump (charging
side between this pin and Ccp B.
Outputs High level in 4W1-2, 2W1-2, W1-2, or
1-2 Phase Excitation mode with electrical angle
of 0° (phase B: 100%, phase A: 0%).
In 2-Phase Excitation mode, outputs High level
with electrical angle of 0° (phase B: 100%,
phase A: 100%).
Detects thermal shut down (TSD) and outputs
High level.
