Freescale Semiconductor (NYSE:FSL)(NYSE:FSL.B) 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 SMARTMOSTM 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. MC34929 features Single-supply operation (8V�28V)
Efficiently drives three-phase BLDC motors up to 1A Autonomous BLDC
control without requiring an MCU interface Built-in hall sensors
controlled-supply (VH) Three-phase hall sensors interface Two
tachometer outputs (1X and 3X hall frequency) Adjustable maximum
current limit (torque limiting) Adjustable stalled rotor detection
and protection Short circuit detection and protection
Over-temperature detection and thermal shutdown Under-voltage
detection and shutdown Low-profile, compact quad flat no-lead (QFN)
4x4x1mm package Restriction of hazardous substances (RoHS)
compliant Pricing and availability The MC34929 is available in
production quantities at a suggested resale price of $1.42 (USD) in
10,000-piece quantities. The MC34929 evaluation boards are
available now for a suggested resale price of $90 (USD). The
KIT34929EGEVBE development tool incorporates digital I/O, making it
easy to use with an MCU in a closed-loop motor control system. For
