Product Details

The LTC4441/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 <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.

The LTC4441 is available in a thermally enhanced 10-lead MSOP package. The LTC4441-1 is the SO-8 version without the blanking function.
