BCD technology, which combines isolated DMOS Power Transistors with CMOS and bipolar c ir cuits 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-dis sipa­tive overcurrent detection on the high side Power MOSFETs plus a diagnostic output that can be easily used to implement the overcurrent protection.
