a 4919 Three-Phase MOSFET Driver with Integrated Regulator Description Features an D Bene Fits The A4919 is a three-phase controller for use with N-channel High-current 3-phase gate drive for N-channel MOSFETs external power MOSFETs. 5.5 to 50 V supply voltage range Regulated logic supply voltage output option A unique charge pump regulator provides full (>10 V) gate drive Low-current Sleep mode option at power supply voltages down to 7 V and allows the A4919 Motor phase short-to-supply and short-to-ground detection to operate with reduced gate drive at power supply voltages Cross-conduction protection down to 5.5 V. A bootstrap capacitor is used to provide the Undervoltage, overtemperature monitors above power supply voltage required for N-channel MOSFETs. One logic-level input is provided for each of the six power a pplications MOSFETs in the 3-phase bridge, allowing motors to be driven Lawn and garden equipment with any commutation scheme defined by an external controller. Battery-operated power tools The power MOSFETs are protected from cross-conduction by Industrial grinders integrated crossover control. Continuous positive airway pressure (CPAP) machines Vacuum cleaners Motor phase short-to-supply and short-to-ground detection is provided by independent drain-source voltage monitors on each MOSFET. Short faults, supply undervoltage, and chip package : overtemperature conditions are indicated by a single open- 28-pin TSSOP drain fault output. with exposed thermal pad (suffix LP) Product variants incorporating a low dropout (LDO) regulator to source either 5.0 V or 3.3 V to external circuitry are available. 28-terminal The A4919 is supplied in a 28-pin TSSOP power package with 5 mm 5 mm QFN exposed thermal pad (package type LP) and a 28-terminal with exposed thermal pad 5 mm 5 mm 0.90 mm QFN package with exposed thermal (suffix ET) pad. Both packages are lead (Pb) free, with 100% matte-tin leadframe plating (suffix T).
