Application information
In normal operating conditions the DIAG
device. This pin must be externally pulled high.
PWM pin usage: In all cases, a “0” on the PWM pin turns off both LS
When PWM rises back to “1”, LS

The value of the blocking capacitor (C) depends on the application conditions and defines
voltage and current ripple on supply line at PWM operation. Stored energy of the motor
inductance may fly back into the blocking capacitor, if the bridge driver goes into 3-state.
This causes a hazardous overvoltage if the capacitor is not big enough. As basic orientation,
500 µF per 10 A load current is recommended.
