Overview
The L6230QTR, produced by STMicroelectronics, is a DMOS fully integrated three-phase motor driver designed for driving brushless DC (BLDC) motors. This device is optimized for Field Oriented Control (FOC) applications due to its independent current sensing capabilities. Realized in BCDmultipower technology, the L6230 combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip, offering a comprehensive solution for motor control systems.
