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.
The L6235 is a DMOS fully integrated three‑phase motor driver designed for brushless DC motors. It includes a three‑phase DMOS bridge, constant‑off‑time PWM current controller, Hall‑effect sensor decoding logic, brake function, and integrated fast free‑wheeling diodes. The device operates from 8 V to 52 V supply voltage and supports up to 100 kHz switching frequency.
The document contains absolute maximum ratings, recommended operating conditions, detailed pin descriptions for the PowerDIP24, PowerSO36 and PowerS036 packages, electrical and thermal characteristics, circuit diagrams for the charge pump and logic inputs, and mechanical dimensions. It also provides typical application notes such as charge‑pump component values and protection circuitry.
