Dual High-Speed 1.5A MOSFET Drivers
General Description
The MAX4426/4427/4428 are dual monolithic MOSFET
drivers designed to translate TTL/CMOS inputs to high
voltage/current outputs. The MAX4426 is a dual inverting
power MOSFET driver. The MAX4427 is a dual noninvert-
ing power MOSFET driver, and the MAX4428 contains
one inverting section and one noninverting section.
Delay times are nearly independent of V
DD
(see
Typical
Operating Characteristics).
High-current output drivers
rapidly charge and discharge the gate capacitance of
even the largest power MOSFETs to within millivolts of
the supply rails. This produces the power MOSFETs'
minimum on resistance. The MAX4426/4427/4428's high
speed minimizes power losses in switching power sup-
plies and DC-DC converters.
