5 Description (continued)

The device implements a standard control interface which includes PWM input (speed command), FG output (speed feedback), FR input (forward and reverse direction control), and RD output (motor lock indicator).

The DRV10970 device supports both 30° and 0° Hall placements (with respect to the corresponding phase BEMF). The device implements trapezoidal drive mode to address higher power requirement.

The DRV10970 device determines the rotor lock condition based on the absence of Hall input switching. The device will try again to spin the motor after an adjustable auto-retry time which can be configured by a capacitor connected to the RETRY pin.

The device incorporates multiple protection features: overcurrent, undervoltage, overtemperature, and locked rotor conditions to improve the system robustness.

The DRV10970 is packaged in a thermally-enhanced 24-pin TSSOP package (eco-friendly: RoHS and no Sb/Br).
