MC1131A - Advanced Brushless Motor Control Chipset

Download the MC1131A datasheet PDF. This datasheet also covers the MC1231A variant, as both devices belong to the same advanced brushless motor control chipset family and are provided as variant models within a single manufacturer datasheet.

General Description

The MC1231A is a dedicated motion processor which functions as a complete chip-based motor controller.

Packaged in a 2-IC chipset, this device performs trajectory generation, servo loop closure, and sinusoidal commutation.

Key Features

  • Supports 3-phase as well as 2-phase brushless motors Performs trajectory generation, servo loop closure, and commutation Ultra-smooth sinusoidal commutation Open or closed loop operation Software and feature-compatible with other 1st generation PMD chipsets Available in 1 or 2 axis configurations 32-bit position, velocity, acceleration and jerk trajectory profile registers Choice of S-curve, trapezoidal, or contoured velocity profile modes Electronic Gearing Two travel-limit switches per axis Ch.
