1 / 23 page  Document Number: MC34929 Rev. 7.0, 11/2006 Freescale Semiconductor Advance Information * This document contains certain information on a new product. Specifications and information herein are subject to change without notice. © Freescale Semiconductor, Inc., 2006. All rights reserved. Brushless DC 1.0 AMP 28 VOLT Motor Driver IC 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 accommodates several modes of operation, including: Forward (CW), Reverse (CCW), Run/Stop, Braking, Variable Speed (External PWM), and Torque Limit (maximum-current-limit) modes. Features • Single-Supply Operation (8V–28V) • Built-in Hall Sensors Controlled-Supply (VH) • 3-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 • Undervoltage Detection and Shutdown • Pb-Free Packaging Designated by Suffix Code EP.
