门驱动器 85V Half Bridge MOSFET Driver

85V Half-Bridge MOSFET Driver with Adaptive Dead Time  and Shoot-Through Protection

General Description MIC4605-1YM

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.
