LTC4441/LTC4441-1

N-Channel MOSFET

Gate Driver

FEATURES

DESCRIPTIO

The LTC^®4441/LTC4441-1 is an N-channel MOSFET gate

driver that can supply up to 6A of peak output current. The

chip is designed to operate with a supply voltage of up to

25V and has an adjustable linear regulator for the gate

drive. The gate drive voltage can be programmed between

5V and 8V.

■

6A Peak Output Current

■

Wide V_INSupply Range: 5V to 25V

■

Adjustable Gate Drive Voltage: 5V to 8V

■

Logic Input can be Driven Below Ground

■

30ns Propagation Delay

■

Supply Independent CMOS/TTL Input Thresholds

■

Undervoltage Lockout

The LTC4441/LTC4441-1 features a logic threshold driver

input. This input can be driven below ground or above the

driver supply. A dual function control input is provided to

disable the driver or to force the chip into shutdown mode

with <12µA of supply current. Undervoltage lockout and

overtemperature protection circuits will disable the driver

output when activated. The LTC4441 also comes with an

open-drain output that provides adjustable leading edge

blanking to prevent ringing when sensing the source

current of the power MOSFETs.

Power Supplies

The LTC4441 is available in a thermally enhanced 10-lead

MSOP package. The LTC4441-1 is the SO-8 version with-

out the blanking function.
