Overview
The L6206PD, produced by STMicroelectronics, is a DMOS dual full bridge driver designed for motor control applications. It is realized in BCD technology, combining isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. This device is available in PowerSO36 and SO24 (20 + 2 + 2) packages. Key features include thermal shutdown, non-dissipative overcurrent detection on the high-side power MOSFETs, and a diagnostic output for overcurrent protection implementation.
