See all from this product rangeProduct Overview
The A4919 is a three-phase controller for use with N-channel external power MOSFETs. A unique charge pump regulator provides full gate drive at power supply voltages down to 7V and allows the A4919 to operate with reduced gate drive at power supply voltages down to 5.5V. A bootstrap capacitor is used to provide the above power supply voltage required for N-channel MOSFETs. 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.
- High-current 3-phase gate drive for N-channel MOSFETs
- 5.5V to 50V 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
