MIC4605-2YMT-TR Datasheet PDF - Microchip

The MIC4605 is an 85V half-bridge MOSFET driver that features adaptive-dead-time and shoot-through protection. The adaptive-dead-time circuitry actively monitors the halfbridge outputs to minimize the time between high-side and low-side MOSFET transitions, thus maximizing power efficiency. Anti-shoot-through circuitry prevents erroneous inputs and noise from turning both MOSFETS on at the same time. The MIC4605 also offers a wide 5.5V to 16V operating supply range to maximize system efficiency. The low 5.5V operating voltage allows longer run times in batterypowered applications. Additionally, the MIC4605"s adjustable gate drive sets the gate drive voltage to VDD for optimal MOSFET RDS(ON), which minimizes power loss due to the MOSFET"s RDS(ON).
