LTC4441IMSE#PBF

LTC4441 is an N-channel MOSFET gate driver that can supply upto 6A of peak output current. The chip is designed to operate with a supply voltage of 5V to 25V and has an adjustable linear regulator for the gate drive. The gate drive voltage can be programmed between 5V and 8V. It 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 <lt/>12µA of supply current. Undervoltage lockout and overtemperature protection circuits will disable the driver output when activated. It 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. It is used in applications such as power supplies, motor/relay control, line drivers, charge pumps etc.
