Freescale Semiconductor has introduced a three-phase brushless DC (BLDC) motor driver integrated circuit (IC) designed to help drive small motors reliably with reduced board space. The MC34929 IC provides a cost-effective, small-footprint BLDC motor driver solution for a variety of consumer, portable and office equipment applications containing small motors.
The single-chip MC34929 IC has built-in over-temperature, under-voltage and stalled-rotor protection circuitry, making it ideal for small-motor applications. The MC34929 operates efficiently with supply voltages from 8 V to 28 V and provides continuous motor drive current up to 1A.
Designed with a built-in three-phase hall-effect sensors interface and a hall sensors voltage supply, the MC34929 motor driver IC can operate BLDC motors autonomously with a pushbutton or switch interface or under the control of an external microcontroller (MCU), such as Freescale’s 8-bit MC9S08QG8CDTE MCU. Its state machine accommodates several modes of operation, including clockwise, counterclockwise, run/stop, brake, variable speed and torque current limit.
“Freescale’s MC34929 device provides sophisticated analog/mixed-signal integrated functions that result in a highly flexible product that is adaptable and configurable to its environment,” said Arman Naghavi, vice president and general manager of Freescale’s Analog, Mixed-Signal and Power Division. “It allows designers to differentiate their products with functions such as adjustable, autonomous and continuous modes.”
Manufactured with Freescale’s proprietary SMARTMOS(TM) process, the MC34929 has built-in stall detection and protection circuitry, logic level control and various configuration and communication features for active monitoring of operation and increased reliability. Offered in a compact, low-profile 24-pin 4 mm x 4 mm x 1 mm ultra-thin QFN package, the MC34929 is ideal for industrial, home and office electronics applications that require a compact BLDC motor driver solution.
