Typical Operating Circuit

General Description

The MAX4426/MAX4427/MAX4428 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

noninverting power MOSFET driver, and the MAX4428

contains one inverting section and one noninverting

section. Delay times are nearly independent of V

(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/

MAX4427/MAX4428's high speed minimizes power loss-

es in switching power supplies and DC-DC converters.

MAX4426/MAX4427/MAX4428 Dual High-Speed 1.5A MOSFET Drivers Applications Information The MAX4426/MAX4427/MAX4428 have easy-to-drive inputs. However, these inputs must never be allowed to stay between VIH and VIL for more than 50ns. Unused inputs should always be connected to ground to minimize supply current. Drivers can be paralleled on the MAX4426 or MAX4427 by tying both Inputs together and both outputs together.
