STMicroelectronics L6235 Manuals

L6235 is a three-phase BLDC motor driver that integrates isolated DMOS power transistors, CMOS and bipolar circuits on the same chip, and features a constant off time PWM current controller, a three-phase DMOS bridge, and a decoding logic for single-ended hall sensors that generate the required sequence for the power stage.

This datasheet introduces the EVAL6235PD demonstration board's features and characteristics, including operating voltage range, output current, operating frequency, overcurrent protection, PWM controller, Hall effect decoding logic, brake function, TACHO output, suitability, etc.

The L6235 is a three-phase BLDC motor driver with overcurrent protection. It is made using MultiPower-BCD technology and integrates isolated DMOS power transistors, CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a three-phase BLDC motor, including: a three-phase DMOS bridge, a constant off time PWM current controller and the decoding logic for single ended hall sensors that generates the required sequence for the power stage. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6235 features a non-dissipative overcurrent protection on the high side Power MOSFETs and thermal shutdown.
