This devise does not guarantee the electrical function above TSD function temperature range. 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 150C. Therefore, this devise must function under Tj maximum 150C condition.

PWM Function Description
Chopping PWM control is applied to supply driving current to the motor in proportion to the analog-voltage input. 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.

Note: When the B1 pin of the M63154AFP is set low or left open-circuit, short braking operation is applied to the M63154AFP when the motor is turned off. When the B1 pin is fixed high (5 V), this operation is not applied. For directions of rotation in the table at left, see the timing chart on page 12.

OSCC Connecta Output Voltage Function
The OFF time of the current-chopper is determined by the capacitance connected to the OSCC pin and the resistance connected to the OSCR pin. The calculation is as follows: Toff = 0.9 [V] x C [F] / (1.25 [V] / 2R [k]

The current from the RS pin is detected at the FLT pin. 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.
