PRODUCTION DATA
To increase the robustness of gate driver over noise transient and accidental small pulses on the input pins, for example, IN+, IN–, RST/EN, a 40-ns deglitch filter filters out the transients and ensures there is no faulty output responses or accidental driver malfunctions. When the IN+ or IN– PWM pulse is smaller than the input deglitch filter width, TINFIL, there are no responses on the OUT drive signal. Figure 6-3 and Figure 6-4 show the IN+ pin ON and OFF pulse deglitch filter effect. Figure 6-5 and Figure 6-6 show the IN– pin ON and OFF pulse deglitch filter effect.
