PWM CURRENT CONTROL
The output current is sensed and controlled independently in each bridge by an external sense resistor (RFN),
internal comparator, and mono-stable multi-vibrator.
When the bridge is turned ON, the current increases in the motor winding and flows through the external sense
resistor until the sense voltage (VNF) reaches the level set at the comparator input: Vref / 5. The comparator then
triggers the mono-stable multivibrator, which turns OFF the lower transistor of the bridge.
The OFF time is determined by the external RC timing components of the monostable multivibrator:
tOFF ≈ 1.1 CR.
The approximate value of the current limiting (IO) is given by the following:
IO = (Vref / 5) / RNF0.05.
