The L6206 is a dual full bridge driver from STMicroelectronics. It is designed for motor control applications and uses MultiPower-BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. Available in PowerDIP24 (20+2+2), PowerSO36 and SO24 (20+2+2) packages, the L6206 features thermal shutdown and a non-dissipa- tive overcurrent detection on the high side Power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.
The L6206 is a DMOS dual full‑bridge driver designed for motor‑control applications. It integrates two independent power MOS full bridges with programmable over‑current detection, thermal shutdown, and fast free‑wheeling diodes.
The handbook includes absolute maximum ratings, recommended operating conditions, thermal data, pin‑out tables, electrical characteristics, circuit description, charge‑pump details, logic input behavior, and mechanical dimensions, helping designers implement the driver in bipolar stepper, DC, or quad‑motor systems.
