BCD technology, which combines isolated DMOS
Power Transistors with CMOS and bipolar circuits on
the same chip. The device also includes two inde-
pendent constant off time PWM Current Controllers
that performs the chopping regulation. Available in
PowerDIP24 (20+2+2), PowerSO36 and SO24
(20+2+2) packages, the L6207 features a non-dissi-
pative overcurrent protection on the high side Power
MOSFETs and thermal shutdown.

Logic Input (6)
Bridge A Enable. LOW logic level switches OFF all Power
MOSFETs of Bridge A. This pin is also connected to the
collector of the Overcurrent and Thermal Protection
transistor to implement over current protection.
If not used, it has to be connected to +5V through a
resistor.
Analog Input Bridge A Current Controller Reference Voltage.
Do not leave this pin open or connect to GND.
(6) Also connected at the output drain of the Over current and Thermal protection MOSFET. Therefore, it has to be driven putting in
series a resistor with a value in the range of 2.2KΩ - 180KΩ, recommended 100KΩ.

be bigger than tRCRISE for allowing a good current regulation by the PWM stage. Furthermore, the on time tON
can not be smaller than the minimum on time tON(MIN).

tRCRISE = 600 · COFF
Figure 10 shows the lower limit for the on time tON for having a good PWM current regulation capacity. It has to
be said that tON is always bigger than tON(MIN) because the device imposes this condition, but it can be smaller
than tRCRISE - tDT. In this last case the device continues to work but the off time tOFF is not more constant.
So, small COFF value gives more flexibility for the applications (allows smaller on time and, therefore, higher
switching frequency), but, the smaller is the value for COFF, the more influential will be the noises on the circuit
performance.
