The MIC4606 is an 85V full-bridge MOSFET driver that features adaptive dead time and shoot-through protection. The adaptive dead time circuitry actively monitors both sides of the full-bridge to minimize the time between high-side and low-side MOSFET transitions, thus maximizing power efficiency. Antishoot-through circuitry prevents erroneous inputs and noise from turning both MOSFETs of each side of the bridge on at the same time.
The MIC4606 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 battery-powered applications. Additionally, the MIC4606'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).
The MC4606-1 features four independent inputs while the MIC4606-2 utilizes two PWM inputs, one for each side of the H-bridge. The MIC4606-1 and MIC4606-2 are available in a 16-pin 4mm x 4mm QFN package with an operating temperature range of -40°C to 125°C.
