Removal
C 1
In noise sensitive applications, both conducted and radiated EMI can
be reduced significantly by controlling the MOSFET's turn-on and
turn-off times.
Figure 22. Controlled MOSFET Drive
V CC = 15V
The totem-pole outputs can furnish negative base current for
enhanced transistor turn-off, with the addition of capacitor C 1 .

Output Load Regulation
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.
