MC34921AE

马达/运动/点火控制器和驱动器 DUAL PWM DC MOTOR DRIVE

Configurable Motor Driver IC with Power Supplies

The 34921 power IC integrates multiple motor drivers, multiple power regulators, and most other analog functions a small consumer motion-enabled product needs. The 34921ís circuitry is fully protected with current limiting, short-circuit shutdown, over-temperature, over voltage, and under-voltage detection.Supervisory functions can be

read and programmed through a 8-MHz Serial Interface.
