A89307 Automotive BLDC Gate Driver

Designed for battery cooling fans and HVAC systems in EV and hybrid vehicles, Allegro's A89307 offers ultra-low noise and vibration by using a field oriented control (FOC) algorithm to drive continuous sinusoidal current to the load, helping automakers reduce noise and improve battery life. The A89307 includes a hardware-based algorithm, which requires no external sensors or software development; the user simply selects parameters using a simple GUI interface and loads them into the IC’s on-chip E2EPROM.

With only five external components, the A89307 helps designers lower material costs by reducing BOM components and facilitating very small system footprints for in-motor PCBs. The A89307 is available in a small 5 mm x 5 mm 28L wettable flank QFN package. Its fully integrated algorithm can even eliminate the need for a separate microprocessor.
