In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers are increasingly adopting a new trend: Replacing multiple magnetic Hall-effect latch sensor devices with a single Hall-effect magnetic angle sensor device for motor-commutation feedback. This trend is particularly evident in the automotive and industrial markets, where use of brushless direct-current (BLDC) motors is on the rise. Another similar trend in certain automotive and industrial applications is the shift from expensive, large, and power-consuming optical encoders and resolvers to magnetic angle position sensors to provide motor-commutation feedback...
