MICROCHIP MIC4605-2YM-T5

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 half-bridge outputs to minimize the time between high-side and low-side MOSFET transitions, thus maximizing power efficiency. Shoot-through protection 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 battery-powered applications. Additionally, the MIC4605 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 MIC4605 is available in an 8-pin SOIC package and a tiny 10-pin 2.5 mm×2.5 mm TDFN package. Both packages have an operating junction temperature range of -40°C to +125°C.
