The outputs can be PWM controlled from an external source. This is typically done by holding one input high while applying a PWM
pulse train to the other input. The maximum PWM frequency obtainable is a compromise between switching losses and switching
frequency. Refer to Typical Switching Waveforms,
The Maximum Switching Frequency during active current limiting is internally implemented. The internal control produces a constant
OFF-time PWM of the output. The output load current effects the Maximum Switching Frequency.
Output Delay is the time duration from the midpoint of the IN1 or IN2 input signal to the 10% or 90% point (dependent on the transition
direction) of the OUT1 or OUT2 signal. If the output is transitioning High-to-Low, the delay is from the midpoint of the input signal to the
90% point of the output response signal. If the output is transitioning Low-to-High, the delay is from the midpoint of the input signal to
the 10% point of the output response signal. See
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. See
Parameter is guaranteed by design but not production tested.
Disable Delay Time is the time duration from the midpoint of the D (disable) input signal to 10% of the output tri-state response. See
