BUY LM629N-8/NOPB https://www.utsource.net/itm/p/860383.html
The LM629N-8/NOPB 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.
Description: The LM629N-8/NOPB is a high performance, monolithic, servo loop motor controller designed to provide closed loop control of brushless DC motors. Features: - High performance, monolithic, servo loop motor controller - Closed loop control of brushless DC motors - Low power consumption - Programmable current limit - Programmable speed limit - Programmable acceleration and deceleration - On-chip voltage regulator Application: The LM629N-8/NOPB is suitable for applications such as robotics, medical equipment, industrial automation, and other applications requiring precise motor control.
