Micrel Semiconductor – MIC4606, MIC2290 and MIC5225: What do Motor Designers Care about? Reliability and Efficiency

Micrel_July2014_pg6amicrel-logo
The MIC4606 Full-Bridge MOSFET Driver with Anti Shoot-Through and Adaptive Dead-Time Circuitry Addresses Both Requirements and More.

The MIC4606 uses a combination of active sensing and passive delay to ensure that both MOSFETs are not on at the same time. The closed loop circuitry assures that there is no shoot-through and minimizes the Dead-Time between each Half-Bridge MOSFETs. The MIC4606 also offers a wide 5.5V to 16V operating supply range to maximize system efficiency and longer run times in battery-powered applications.
