The totem−pole outputs can furnish negative base current for enhanced

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 turn−on and

turn−off times.
