Connecting the TB6548F/FG (or TB6537P/PG/F/FG) to the TA84006F/FG allows electric motors to be controlled
by PWM.
Note 4: In Prohibit Mode, the output power transistor goes into vertical ON mode and through current may damage
the circuit. Do not use the TA84006F/FG in this mode.
This mode is not actuated when the TA84006F/FG is connected to the TB6548F/FG or TB6537P/PG/F/FG,
but can be triggered by input noise during standalone testing.

<Lower PWM>
Connecting the TA84006F/FG to the TB6537P/PG/F/FG controls the lower PWM.
At chopping ON, the diagonally output power transistors are ON.
At chopping OFF, the lower transistor is OFF, regenerating the motor current via the upper diode
(incorporating the Pch-MOS).
