ALLEGRO MICROSYSTEMS A4919GLPTR5T Three-Phase MOSFET Driver
The A4919 is a high-current, three-phase gate driver designed for use with N-channel external power MOSFETs. It features a charge pump regulator that provides full gate drive at supply voltages as low as 7V, enabling operation with reduced gate drive down to 5.5V. A bootstrap capacitor supplies the necessary voltage for N-channel MOSFETs. The device includes one logic-level input for each of the six MOSFETs in the three-phase bridge, allowing motor control with any commutation scheme via an external controller. Integrated crossover control protects against cross-conduction, and additional features include phase short detection, undervoltage and overtemperature monitoring, a regulated logic supply output option, and a low-current sleep mode. Suitable for industrial, power management, and consumer electronic applications.
