MIC4605 MOSFET Gate Drive

Microchip's MIC4605 device is an 85 V half-bridge MOSFET gate driver with 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, maximizing power efficiency. Anti-shoot-through circuitry prevents erroneous inputs and noise from turning both MOSFETs on simultaneously. This device also offers a wide operating supply range of 5.5 V to 16 V to maximize system efficiency. The low 5.5 V operating voltage allows longer run times in battery-powered applications. The MIC4605's adjustable gate drive also sets the gate drive voltage to V_DD for optimal MOSFET R_DS(ON), which minimizes power loss due to the MOSFET’s R_DS(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.
