PRODUCTION DATA
In order to increase the robustness of gate driver over noise transient and accidental small pulses on the input pins, i.e. IN+, IN–, RST/EN, a 40ns deglitch filter is designed to filter out the transients and make sure 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 will be no responses on OUT drive signal. Figure 6-3 and Figure 6-4 shows the IN+ pin ON and OFF pulse deglitch filter effect. Figure 6-5 and Figure 6-6 shows the IN– pin ON and OFF pulse deglitch filter effect.
