Figure 22. Controlled MOSFET Drive
Figure 23. Bipolar Transistor Drive
In noise sensitive applications, both conducted and radiated EMI can
be reduced significantly by controlling the MOSFET’s turn–on and
turn–off times.
The totem–pole outputs can furnish negative base current for
enhanced transistor turn–off, with the addition of capacitor C1.

The capacitor’s equivalent series resistance limits the Drive Output Current to 1.5 A. An
additional series resistor may be required when using tantalum or other low ESR capacitors.
