STMicroelectronics L6235 Three-Phase Motor Driver Datasheet
The L6235 is a DMOS fully integrated three-phase motor driver designed to drive three-phase BLDC motors. Realized in MultiPower-BCD technology, it combines isolated DMOS power transistors with CMOS and bipolar circuits on a single chip. The device includes all necessary circuitry for motor control, such as a three-phase DMOS bridge, a constant off time PWM current controller, and decoding logic for single-ended Hall sensors.
