3.0
The descriptions of the pins are listed in
TABLE 3-1:
3.1
The MOSFET driver inputs are a high-impedance TTL/
CMOS compatible input. The inputs also have hystere-
sis between the high and low input levels, allowing
them to be driven from slow rising and falling signals
and to provide noise immunity.
3.2
Outputs A and B are CMOS push-pull outputs that are
capable of sourcing and sinking 4.0A of peak current
(V
gate of the MOSFET will stay in the intended state even
during large transients. These outputs also have a
reverse latch-up rating of 1.5A.
3.3
V
has a voltage range of 4.5V to 18V. This input must be
decoupled to ground with a local ceramic capacitor.
This bypass capacitor provides a localized low-imped-
ance path for the peak currents that are to be provided
to the load.
3.4
Ground is the device return pin. The ground pin(s)
should have a low impedance connection to the bias
supply source return. High peak currents will flow out
the ground pin(s) when the capacitive load is being
discharged.

The ENB_A pin is the enable control for Output A. This
enable pin is internally pulled up to V
operation and can be left floating for standard
operation. When the ENB_A pin is pulled below the
enable pin Low Level Input Voltage (V
will be in the off state regardless of the input pin state.
3.6
The ENB_B pin is the enable control for Output B. This
enable pin is internally pulled up to V
operation and can be left floating for standard
operation. When the ENB_B pin is pulled below the
enable pin Low-Level Input Voltage (V
will be in the off state regardless of the input pin state.
3.7
The exposed metal pad of the DFN package is not
internally connected to any potential. Therefore, this
pad can be connected to a ground plane or other
copper plane on a printed circuit board to aid in heat
removal from the package.
