Description
The L6206Q device is a DMOS dual full bridge
driver designed for motor control applications,
developed using BCDmultipower technology,
which combines isolated DMOS power transistors
with CMOS and bipolar circuits on the same chip.
Available in a VFQFPN48 7 x 7 package, the
L6206Q device features thermal shutdown and
a non-dissipative overcurrent detection on the
high side Power MOSFETs plus a diagnostic
output that can be easily used to implement the
overcurrent protection.
