Description
The L6207 device is a DMOS dual full bridge
designed for motor control applications, realized
in BCD 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 PowerSO36 and SO24
(20 + 2 + 2) packages, the L6207 device features
a non-dissipative overcurrent protection on the
high-side Power MOSFETs and thermal
shutdown.
Features
Operating supply voltage from 8 to 52 V
5.6 A output peak current (2.8 A DC)
RDS(ON) 0.3 typ. value at Tj = 25 °C
Operating frequency up to 100 KHz
Non-dissipative overcurrent protection
Dual independent constant tOFF PWM current
controllers
Slow decay synchronous rectification
Cross conduction protection
