Analog Devices Inc. LTC4449EDCB is a high-speed, half-bridge gate driver IC designed for demanding power conversion applications. This non-inverting driver is optimized for driving N-channel MOSFETs, featuring robust peak output currents of 3.2A sourcing and 4.5A sinking. The device supports a bootstrap voltage up to 42V, allowing for efficient high-side drive. With a wide supply voltage range of 4V to 6.5V and logic thresholds at 3V (VIL) and 6.5V (VIH), it integrates seamlessly into various control schemes. The LTC4449EDCB exhibits fast switching characteristics with typical rise and fall times of 8ns and 7ns, respectively. Packaged in an 8-DFN (2x3) with an exposed pad for enhanced thermal performance, this component is suitable for industrial, automotive, and consumer electronics power systems.
