Description
Designed to control three-phase brushless DC motors, the A4923 is capable of high-current gate drive for an all N-channel power MOSFET 3-phase bridge.
Sinusoidal current control is employed via output PWM, to minimize vibration, noise, and torque ripple.
Internal circuit protection includes thermal shutdown with hysteresis, over-current, and dead-time protection. Special power up sequencing is not required.
The A4923 is supplied in a 32 terminal...
