The HX4423/4424/4425 driver is pri
drive power MOSFE

s
, and it is ideal fo
loads such as capacitors, resistors, or ind
require low impedance, peak current, and fast s
times. It can be used with heavy
–
duty clock
coaxial cables, or piezoelectric transducers. The on
limitation is that the total power dissipated in the driver
must be kept within the maximum power dissipation limit
of the package.

Inputs A and B
MOSFET driver inputs A and B are high
–
impedance, TTL
se inputs also have
300mV of hysteresis between the high and low thresholds tha
when the rise and
fall time of the input signal is very slow.
Ground (GND)
Ground is the device return pin. The Ground pin(s) should have a low
–
i
s supply
source return. High peak current flows out the Ground pin(s) when the cap
.
Output A and B
MOSFET driver outputs A and B are low
–
impedance, CMOS push
–
pull style outp
devices are of equal strength, making the rise and fall times equivalent. Output A
unbiased or floating.
Supply Input (VDD)
The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 25V with resp
pin. The VDD input should be bypassed with local ceramic capacitors. The value of these capa
chosen based on the capacitive load that is being driven. A value of 1.0 μF is suggested.
Exposed Metal Pad
The exposed metal pad of the DFN
–
S 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 (PCB), to aid in heat
removal from the package.
