The totempole outputs can furnish negative base current for enhanced
transistor turnoff, with the addition of capacitor C
1
.
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.
In noise sensitive applications, both conducted and radiated EMI can
be reduced significantly by controlling the MOSFET’s turnon and
turnoff times.
