MAX4427/MAX4428

Dual High-Speed 1.5A MOSFET Drivers

General Description

Features

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

S Fast Rise and Fall Times: Typically 20ns with

(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.

Power Dissipation

Applications Information

The MAX4426/MAX4427/MAX4428 have easy-to-drive

inputs. However, these inputs must never be allowed to

The MAX4426/MAX4427/MAX4428 power dissipation

consists of input inverter losses, crowbar current through

the output devices, and output current (either capacitive

or resistive). The sum of these must be kept below the

maximum power dissipation limit.

IH

IL

inputs should always be connected to ground to mini-

mize supply current. Drivers can be paralleled on the

MAX4426 or MAX4427 by tying both Inputs together and

both outputs together.

The DC input inverter supply current is 0.2mA when both

inputs are low and 2mA when both inputs are high. The

crowbar current through an output device making a tran-

sition is approximately 100mA for a few nanoseconds.

This is a small portion of the total supply current, except

for high switching frequencies or a small load capaci-

tance (100pF).

Supply bypassing and grounding are extremely impor-

tant with the MAX4426/MAX4427/MAX4428, as the peak

supply current can be as high as 3A, which is twice the

peak output current. Ground drops are a form of nega-

tive feedback with inverters, and hence will degrade the

delay and transition time of the MAX4426/MAX4428.

The MAX4426/MAX4427/MAX4428 power dissipation

when driving a ground-referenced resistive load is:

Suggested bypass capacitors are a 4.7µF (low ESR)

capacitor in parallel with a 0.1µF ceramic capaci-

tor, mounted as close as possible to the MAX4426/

MAX4427/MAX4428. Use a ground plane if possible or

separate ground returns for inputs and outputs. Output

voltage ringing can be minimized with a 5Ω to 20Ω resis-

tor in series with the output, but this will degrade output

transition time. Ringing may be undesirable due to the

large current that flows through capacitive loads when

the voltage across these loads transitions quickly.

where D is the percentage of time the MAX4426/

is the MAX4426/MAX4427/MAX4428 maximum on

resistance, and I is the MAX4426/MAX4427/

MAX4428 load current.

For capacitive loads. the power dissipation is:

Operation at the upper end of the supply voltage range

(> 15V) requires that a capacitance of at least 50pF be

present at the outputs. This prevents the supply voltage

provided to the die (which can be different from that

seen at the supply pin) from exceeding the 20V absolute

maximum rating, due to overshoot. Since at least 50pF

of gate capacitance is present in all higher power FETs,

this requirement is easily met.
