STMicroelectronics L6230
The L6230 is a DMOS fully integrated 3-phase motor driver with overcurrent protection optimized for FOC application thanks to the independent current senses. Available in Power SO36 and VFQFPN32 packages, the L6230 features a nondissipative overcurrent protection on the high-side power MOSFET and thermal shutdown.FEATURES
