MIC4605 85V Half-Bridge MOSFET Drivers with Adaptive Dead Time and Shoot-Through Protection General Description Features The MIC4605 is an 85V half-bridge MOSFET driver that 5.5V to 16V gate drive supply voltage range features adaptive-dead-time and shoot-through protection. Advanced adaptive-dead-time The adaptive-dead-time circuitry actively monitors the half- Intelligent shoot-through protection bridge outputs to minimize the time between high-side and MIC4605-1: Dual TTL inputs low-side MOSFET transitions, thus maximizing power efficiency. Anti-shoot-through circuitry prevents erroneous MIC4605-2: Single PWM input inputs and noise from turning both MOSFETS on at the Enable input for on/off control same time. On-chip bootstrap diode The MIC4605 also offers a wide 5.5V to 16V operating Fast 35ns propagation times supply range to maximize system efficiency. The low 5.5V Drives 1000pF load with 20ns rise and fall times operating voltage allows longer run times in battery- Low power consumption: 135A quiescent current powered applications. Additionally, the MIC4605s Separate high- and low-side undervoltage protection adjustable gate drive sets the gate drive voltage to VDD for optimal MOSFET R , which minimizes power loss DS(ON) 40C to +125C junction temperature range due to the MOSFETs R . DS(ON) Applications The MIC4605 is available in an 8-pin SOIC package and a tiny 10-pin 2.5mm 2.5mm TDFN package. Both Fans packages have an operating junction temperature range of Power inverters 40C to +125C. High-voltage step-down regulators Datasheets and support documentation are available on Half-, full-, and three-phase bridge motor drives Micrels web site at: www.micrel.com.
