REFMOT003 - Reference Design
Automotive Three-Phase Brushless Motor Pre-Driver with Sensor
This reference design is a solution board for a three-phase brass-less sensor-equipped motor pre-driver developed to control automotive air conditioner blower motors and battery cooling fan motors. In addition to the pre-driver, the NchMOS of the output stage and peripheral components for external input setting are integrated on a single board, and the motor can be controlled simply by connecting the power supply (12V typ.) By using noise suppression and S/R adjustment, this product has passed the CISPR 25 Class 5 EMC standard. This product can be used as a reference design for circuit and pattern design when creating PCBs.
- Cleared EMC standard CISPR 25 Class 5 (in-house evaluation)
- 180°current flow (sinusoidal drive)
- Built-in automatic advance function
- Variable speed control function (supports both PWM and DC input)
- Dead time switching
- Various built-in protection functions (OVP, UVLO, OCL, OCP, LOCK, TSD, TXTSD, HALLERR)
This reference design consists of two different boards, with a choice of different sized Nch MOSFETs packages.
