MAX17600–MAX17605

4A Sink /Source Current, 12ns, Dual MOSFET Drivers

General Description

The MAX17600–MAX17605 devices are high-speed

MOSFET drivers capable of sinking /sourcing 4A peak

currents. The devices have various inverting and non-

inverting part options that provide greater flexibility in

controlling the MOSFET. The devices have internal logic

circuitry that prevents shoot-through during output-state

changes. The logic inputs are protected against voltage

spikes up to +14V, regardless of V DD voltage. Propagation

delay time is minimized and matched between the dual

channels. The devices have very fast switching time,

combined with short propagation delays (12ns typ),

making them ideal for high-frequency circuits. The

devices operate from a +4V to +14V single power

supply and typically consume 1mA of supply cur-

rent. The MAX17600/MAX17601 have standard TTL

input logic levels, while the MAX17603 /MAX17604/

MAX17605 have CMOS-like high-noise margin (HNM)

input logic levels. The MAX17600/MAX17603 are dual

inverting input drivers, the MAX17601/MAX17604 are

dual noninverting input drivers, and the MAX17602 /

MAX17605 devices have one noninverting and one

inverting input. These devices are provided with enable

pins (ENA, ENB) for better control of driver operation.

These devices are available in 8-pin (3mm x 3mm) TDFN,

8-pin (3mm x 5mm) F MAX ? , and 8-pin SO packages and
