The Analog Devices Inc. LTC4447IDD-PBF is a dual, high-speed, non-inverting half-bridge gate driver designed for driving N-channel MOSFETs. This component features independent drivers, each capable of sourcing and sinking 3.2A peak output current with typical rise and fall times of 8ns and 7ns respectively. It supports a high-side voltage of up to 42V with a bootstrap capability. The logic operates with VIH of 3V and VIL of 2.5V, and the supply voltage range is 4V to 6.5V. Packaged in a 12-DFN (3x3) with an exposed pad, the LTC4447IDD-PBF is suitable for surface mounting and operates across an industrial temperature range of -40°C to 125°C. This device finds application in power conversion systems, including switch-mode power supplies and motor control circuits.
