Microchip MIC4606-1YML

Description

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. Anti-shoot-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 device’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 MIC4606-1 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 4 mm x 4 mm QFN package, and a 16-pin 4 mm x 5 mm TSSOP package with an operating temperature range of -40°C to +125°C.
