LM629N6 Datasheet PDF - TI

●The LM629N6 is a dedicated Motion-control Processor designed for use with a variety of DC and brushless DC servo motors and other servomechanisms which provide a quadrature incremental position feedback signal. The parts perform the intensive, real-time computational tasks required for high performance digital motion control. The host control software interface is facilitated by a high-level command set. It has an 8-bit output which can drive either an 8-bit or a 12-bit DAC. The components required to build a servo system are reduced to the DC motor/actuator, an incremental encoder, a DAC and a power amplifier. An LM629-based system is similar, except that it provides an 8-bit PWM output for directly driving H-switches. It incorporates an SDA core processor and cells designed by SDA.
