The maximum PWM frequency should be limited to frequencies < 11 kHz in order to allow the internal high side driver circuitry time to
fully enhance the high side MOSFETs.
The internal current limit circuitry produces a constant-OFF-time Pulse Width Modulation of the output current. The output load’s
inductance, capacitance, and resistance characteristics affect the total switching period (OFF-time + ON-time), and thus the PWM
frequency during current limit.
* Output Delay is the time duration from 1.5V on the IN1 or IN2 input signal to the 20% or 80% point (dependent on the transition direction)
of the OUT1 or OUT2 signal. If the output is transitioning HIGH-to-LOW, the delay is from 1.5 V on the input signal to the 80% point of
the output response signal. If the output is transitioning LOW-to-HIGH, the delay is from 1.5 V on the input signal to the 20% point of the
output response signal. See
The time during which the internal constant-OFF time PWM current regulation circuit has tri-stated the output bridge.
The time during which the current regulation threshold is ignored so that the short-circuit detection threshold comparators may have time
to act.
* Disable Delay Time measurement is defined in
Rise Time is from the 10% to the 90% level and Fall Time is from the 90% to the 10% level of the output signal with V
= 3.0 ohm. See
