Functional Descriptions
Voltage-Regulated Bridges: H-SW A to H-SW F
Direct PWM control
Performing drive control by setting the PWM pins High and Low achieves high thermal efficiency.
In PWM constant-current mode, the PWM chopper circuit alternates between on (t1, t5) and short brake (t3).
(To eliminate shoot-through current, a dead time of 0.5
s (typ.) (t2, t4) is inserted when the PWM is turned on
and off.)
The PWM pins should be held High (max
= VCC) when PWM control is not used.
