Main components
1README
BLDC_D28_Drv/README.mdBLDC_D28_Drv
Tiny driver stage for mounting on BLDC motors with 28/29mm diameters.
Highlights:
- Specialized outline for mounting on BLDC motors with 28/29mm diameters. Can also be uesd as a general-purpose 3-phase bridge.
- Features 3 bootstrap half-bridge driver with common footprint. TTL/CMOS logic input compatible.
- Separated power supply for gate driver and motor power makes it capable to drive motors require high volatge.
Status:
Partially verified.
