MIC4605 85V Half-Bridge MOSFET Driver with Adaptive Dead Time and Shoot-Through Protection Features General Description 5.5V to 16V Gate Drive Supply Voltage Range The MIC4605 is an 85V half-bridge MOSFET driver that features adaptive dead time and shoot-through Advanced Adaptive Dead Time protection. The adaptive dead-time circuitry actively Intelligent Shoot-Through Protection: monitors the half-bridge outputs to minimize the time - MIC4605-1: Dual TTL inputs between high-side and low-side MOSFET transitions, - MIC4605-2: Single PWM input thus maximizing power efficiency. Shoot-through Enable Input for On/Off Control protection circuitry prevents erroneous inputs and noise On-Chip Bootstrap Diode from turning both MOSFETS on at the same time. Fast 35 ns Propagation Times The MIC4605 also offers a wide 5.5V to 16V operating Drives 1000 pF Load with 20 ns Rise and supply range to maximize system efficiency. The low Fall Times 5.5V operating voltage allows longer run times in Low-Power Consumption: 135 A Quiescent battery-powered applications. Additionally, the MIC4605 Current devices adjustable gate drive sets the gate drive voltage Separate High-Side and Low-Side Undervoltage to V for optimal MOSFET R , which minimizes DD DS(ON) Protection power loss due to the MOSFETs R . DS(ON) -40C to +125C Junction Temperature Range The MIC4605 is available in an 8-pin SOIC package AEC-Q100 Qualified for the SOIC Package and a tiny 10-pin 2.5 mm x 2.5 mm TDFN package. Both packages have an operating junction temperature Applications range of -40C to +125C.
