AMG-XB404
Fully Integrated Single Motor Controller for Electrical Motors
1. Functional Description of the AMG-XB404
The AMG-XB404 is a feature rich SoC, providing a single chip solution for motor control, including
Digital Motor Control Engine (DMCE), Power Factor Correction (PFC), high level system control
MCU, and Switch Mode Power Supply (SMPS). The IC's multi-core design enables parallel
execution of all system functions while keeping the MCU load to a minimum. The DMCE includes a
processing unit, PWM generator, and power stage driver allowing for sensorless drive. The AMG-
XB404's switching power supply circuit, which includes software adjustable switching frequency,
requires the IC to only have a single, low-grade power supply.
