The Infineon A2C52004004 is an industrial-grade 3-phase brushless DC motor driver ideal for use in heavy-duty industrial applications such as pumps, compressors, blowers, fans and conveyors. It features a three-phase full bridge capable of delivering up to 400A at 24 to 48Vdc, with a maximum switches frequency of 20kHz. The motor can be driven in either full-torque-gear or vector-controlled speed mode with built-in current protection and over-temperature protection. It also features adjustable speed regulation, configurable PWM frequency and multiple operation modes. The device is housed in a compact, robust housing that can be mounted on an aluminum heatsink.
