产品概述

描述

The L6207Q device is a DMOS dual full bridge driver designed for motor control applications, realized in BCDmultipower technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device also includes two independent constant OFF time PWM current controllers that perform the chopping regulation. Available in a VFQFPN48 7 x 7 package, the L6207Q device features thermal shutdown and a non-dissipative overcurrent detection on the high-side Power MOSFETs.
