LV8324C
Overview
The LV8324C is the driver for 24 V single phase BLDC motor. Its target output duty-cycle can be set by input PWM duty cycle. The output duty-cycle curve setting can be stored to the internal nonvolatile memory (NVM). In addition, lead-angle can also be adjusted by the configuration saved in the internal NVM. Thus, it can drive various kinds of motors at high efficiency and low noise.
