The function is guaranteed under maximum junction temperature that is regulated in the Absolute Maximum Rating, so TSD function is a protection circuit for unusual Tj when this devise is used over Tj 150°C. Therefore, this devise must function under Tj maximum 150°C condition.

This IC detects the flow of current to the motor and the power supply continues to supply current until it reaches a level specified in terms of the input voltage (current path 1). At that time, the output transistors are switched, and energy stored in the coil regenerates current for a period determined by the internal off-timer circuit (current path 2). When the timer reaches the specified value, the power supply again starts to supply current. Operation proceeds through repetition of these phases.

This current reaching a value specified by the voltage on the VCTL pin indicates full discharge. After charging, the voltage on the OSCC pin (pin 23) sets the off-period for PWM current-chopping control. Whenever a Hall input switches polarity, the voltage on the OSCC pin is temporarily reset to 0 V. While the voltage on the OSCC pin is 0.9 V or less, the PWM waveforms are off (regenerative operation). Otherwise, PWM waveforms are on. The above timing chart shows the timing with which outputs for the motor are switched on and off during PWM control. Timing for the switching of outputs in response to Hall input varies with the setting of the B1 pin.
