The TIDA-00472 is a discrete IGBT-based three-phase inverter for driving brushless DC (BLDC) motors rated up to 250 W, for example, used in cooker hoods, using a sensor-less, trapezoidal control method. The design provides software implementation for DC bus voltage ripple compensation resulting in 30% reduction in the DC bus capacitor requirement and reduced overall BOM cost. The cycle-by-cycle overcurrent protection feature protects the power stage from large current spikes and the board can work up to 65°C ambient. This design has also been tested to pass EN55014 standards for conducted emissions, Surge and EFT.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
