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 RDSON from the

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 VDD voltage and how much

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.
