(11) Shift to the short brake mode at the PWM1 falling edge.
(12) The normal operation returns by PWM1 = H signal.
(13) Since PWM1 hold "H", the motor drive current is increasing.
(14) Then the operation becomes the short brake mode operation, and the motor drive current is reduced
by PWM1 = L signal.
7.3.2. Thermal Adjustment Function of Current Limitation Control
When the junction temperature Tj rises in the operation of the current limitation control circuit, the
current limitation threshold falls to 2.5A (typ.) after detecting Twar temperature (150°C to 170°C).
The Ilim-L may be also lowered by falling of the threshold of Ilim-H.
