AMIS-30623 LIN Microstepping Motordriver
15.3.6. Charge Pump Monitoring
If the charge pump voltage is not sufficient for driving the high side transistors (due to a failure), an internal HardStop command is
issued. This is acknowledged to the master by raising flag <CPFail> (available with command GetFullStatus).
In case this failure occurs while a motion is ongoing, the flag <StepLoss> is also raised.
15.3.7. Electrical Defect on Coils, Detection and Confirmation
The principle relies on the detection of a voltage drop on at least one transistor of the H-bridge. Then the decision is taken to open the
transistors of the defective bridge.
This allow to detect the following short circuits:
• External coil short circuit
• Short between one terminal of the coil and Vbat or Gnd
• One cannot detect internal short in the motor
Open circuits are detected by 100% PWM duty cycle value during a long time
