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