Output Driver Section
A block diagram of the low-side driver is shown in Figure
3. Low driver impedances allow the external MOSFET to
be turned on and off quickly. The rail-to-rail drive
capability of the output ensures a low R
from the
DSON
external MOSFET.
Redundant Vout pins lower the driver circuit impedance,
which helps increase the drive current and minimize LC
circuit ringing between the MOSFET gate and driver
output.
The slew rate of the output is non-adjustable and
depends only on the V
voltage and how much
DD
capacitance is present at the VOUT pin. The slew rate
at the MOSFET gate can be adjusted by adding a
resistor between the MOSFET gate and the driver
output.
