Allegro Unveils BLDC Motor Controller with Integrated FOC

Allegro Microsystems has introduced the A89307, an advanced automotive-grade BLDC motor controller that integrates a gate driver and field-oriented control (FOC) technology. This new solution offers a complete and efficient platform for brushless DC motor control in automotive systems. The A89307 stands out with its built-in FOC capabilities, enabling precise and energy-efficient motor performance. It also features flexible speed control options to suit various application needs and includes a programmable input-to-output transformer, allowing engineers to fine-tune performance for specific requirements. Designed to streamline development and enhance reliability, the A89307 is poised to support a wide range of automotive motor control applications, from HVAC systems to engine cooling and beyond.

Key features of the A89307

  • Code-free sensorless field-oriented control (FOC) - No software programming
  • Ultra-quiet low speed operation - Reduces audible noise and vibration
  • Proprietary non-reverse fast startup - Improves reliability and reduces audible noise
  • Analog, PWM, Analog, or Clock mode speed control with programmable speed profile
  • Configurable current limit and lock detection - Reduces motor heating
  • Start-up under both forward and reverse windmilling conditions - improves reliability
  • Short-circuit protection (OCP) - protects supply and PCB from burning during MOSFET failure

Key applications of the A89307

  • Battery Cooling Fan
  • HVAC Fan
  • Inverter Cooling Pump
