Figure 4.
Operational Waveforms and Circuit Layout
Figure 5 shows the circuit performance achievable with a single driver (1/2 of the 8-pin IC) driving a 10-nF load.
The input pulsewidth (not shown) is set to 300ns to show both transitions in the output waveform. Note the linear
rise and fall edges of the switching waveforms. This is due to the constant output current characteristic of the
driver as opposed to the resistive output impedance of traditional MOSFET-based gate drivers.
