Analog Devices Inc. presents the LTC4449IDCB-TRMPBF, a dual-output, high-speed, non-inverting half-bridge gate driver. This component is engineered for driving N-channel MOSFETs in half-bridge configurations. It features a peak output current of 3.2A source and 4.5A sink, facilitating rapid switching with typical rise and fall times of 8ns and 7ns, respectively. The driver supports a high-side voltage up to 42V, powered by a supply voltage range of 4V to 6.5V. Input logic levels for VIH and VIL are 6.5V and 3V. The LTC4449IDCB-TRMPBF is housed in a compact 8-DFN (2x3) package with an exposed pad for enhanced thermal performance, suitable for surface mount applications. Operating within a temperature range of -40°C to 125°C (TJ), this device finds application in power supply circuits, motor control, and power conversion systems.
