Prolific PT-30DFT DC Brushless Motor Driver IC Datasheet
The document describes the Prolific PT-30DFT, an integrated circuit designed as a H-Bridge driver for single-coil DC brushless motors. It operates within a supply voltage range of 3V to 18V and features a built-in hysteresis comparator to eliminate noisy oscillations.
Key functional characteristics include motor lock protection that shuts down the driver if the motor is locked for over 0.3 seconds, followed by an automatic restart after 2.1 seconds. The IC also provides Frequency Generation (FG) output and Rotation Detection (RD) alarm outputs to indicate motor status.

Questions answered in these manuals
What happens if the motor is locked?
The driver IC shuts down to drive the coil for over 0.3 seconds, then restarts after 2.1 seconds.
