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 limts the Drive Output Current
to 1.5 A. An additional series resistor may be required when using tantalumor
other low ESR capacitors.
In noise sensitive applications, both conducted and radiated EMI can
be reduced significantly by controlling the MOSFET’s turn–on and
turn–off times.
