AN1178 - DDB094R2 and DDB099 Demo Boards

Diodes Inc.

The automotive industry is undergoing unprecedented change, with the move to electrification and ongoing development in safety devices and autonomous vehicles resulting in an increased demand for semiconductors. DC motors are experiencing exponential growth in areas ranging from simple, low-power brushed versions to high-power brushless DC motors (BLDC). According to Allied Market Research, the Brushless DC motors industry will reach $72.24 Bn by 2030, compared to $33.15 Bn in 2020. This in turn increases the requirement for a variety of motor driver solutions.

Diodes Incorporated (Diodes) has developed two demo boards featuring its automotive ‘Q’ MOSFET and portfolio of gate driver ICs to target BLDC Motor applications in the automotive sector.
