Advance Information

Brushless DC 1.0 AMP 28 VOLT

Motor Driver IC

34929

The 34929 Brushless DC (BLDC) Motor Driver IC is a complete

BLDC motor driver system in one chip. It is designed to efficiently drive

three-phase BLDC motors up to 1A and 28V, and has built in protection

features making it ideal for a variety of consumer, portable, and office

applications containing small motors. It incorporates digital I/O, making

it easy to use with an MCU in a closed-loop motor control system. It has

a built-in Hall-effect sensors interface and a Hall sensors voltage

supply, so it can operate BLDC motors as a stand-alone controller/

driver. Its sophisticated analog/mixed-signal state machine

BRUSHLESS DC MOTOR DRIVER

accommodates several modes of operation, including: Forward (CW),

Reverse (CCW), Run/Stop, Braking, Variable Speed (External PWM),

and Torque Limit (maximum-current-limit) modes.
