Brushless DC motor (BLDC) - controller and driver

Today, a growing number of applications rely on a brushless DC (BLDC) motor, ranging from automotive to industrial applications. Moreover, BLDC motors are used in medical equipment, home appliances, building controls and industrial automation. In each instance, a BLDC motor is chosen for the numerous advantages it offers, including:

• Highest efficiency
• Small motor size
• Light weight
• Longer lifetime
• No maintenance
• No sparking
• Steady operation
• Variable speed

Though a BLDC motor is fairly efficient by nature, designers today face mounting pressure to further enhance their design’s efficiency and stand out on the competitive market. This can be achieved, for example, by reducing overall energy consumption and optimizing thermal management. Reducing the system size and decreasing maintenance can also help produce desirable results.

To overcome these key challenges and design a more efficient brushless DC motor, you need a competent partner by your side. Infineon’s BLDC product offer provides exactly what you are looking for, from power switches to microcontrollers, to dedicated motor control ICs, to gate drivers, to sensors.

In particular, Infineon’s wide selection of Embedded Power ICs suits many brushless DC motor applications, such as window lift, sunroof, wiper, fuel pump, and HVAC fans. Embedded Power ICs minimize the number of external components required and, as system-on-chip solutions, enable a high level of integration. The resulting benefits include space and energy savings, improved overall system reliability and reduced cost.
