The Analog Devices Inc. LTC4447EDD-PBF is a high-speed, non-inverting half-bridge gate driver. Designed for driving N-channel MOSFETs, this component features two independent drivers, each capable of sourcing and sinking 3.2A peak output current. It operates with a supply voltage range of 4V to 6.5V and supports a high-side bootstrap voltage up to 42V. The LTC4447EDD-PBF offers fast switching performance with typical rise and fall times of 8ns and 7ns, respectively. Its low logic voltage thresholds (VIL/VIH of 2.5V/3V) facilitate interfacing with a variety of microcontrollers. This device is housed in a 12-DFN (3x3) exposed pad package, suitable for surface mounting. Applications include DC-DC converters, motor control, and power supply systems.
