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.
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 <12
μ
A 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.
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.
