BD62012AFS General Description

This controller synthesizes the optimal driving signal from hall sensor signals, and outputs the synthesized signal to control the external level shifter and power transistor. The replacement is also easy because of its pin compatibility with BD62011AFS and BD62014AFS. This controller provides optim.
