CIRCUIT DESCRIPTION
POWER STAGES and CHARGE PUMP
The L6206 integrates two independent Power MOS
Full Bridges. Each Power MOS has an Rd-
son=0.3ohm (typical value @ 25°C), with intrinsic
fast freewheeling diode. Cross conduction protection
is achieved using a dead time (td = 1
μ
s typical) be-
tween the switch off and switch on of two Power MOS
in one leg of a bridge.
Using N Channel Power MOS for the upper transis-
tors in the bridge requires a gate drive voltage above
the power supply voltage. The Bootstrapped (Vboot)
supply is obtained through an internal Oscillator and
few external components to realize a charge pump
circuit as shown in Figure 3. The oscillator output
(VCP) is a square wave at 600kHz (typical) with 10V
amplitude. Recommended values/part numbers for
the charge pump circuit are shown in Table1.

A
and EN

are TTL/
CMOS and uC compatible logic inputs. The internal
structure is shown in Fig. 4. Typical value for turn-on
and turn-off thresholds are respectively Vthon=1.8V
and Vthoff = 1.3V.
Pins EN
A
and EN
B
are commonly used to implement
Overcurrent and Thermal protection by connecting
them respectively to the outputs OCD

and OCD

,
which are open-drain outputs. If that type of connec-
tion is chosen, some care needs to be taken in driving
these pins. Two configurations are shown in Fig. 5
and Fig. 6. If driven by an open drain (collector) struc-
ture, a pull-up resistor R
EN
and a capacitor C
EN
are
connected as shown in Fig. 5. If the driver is a stan-
dard Push-Pull structure the resistor R
EN
and the ca-
pacitor C
EN
are connected as shown in Fig. 6. The
resistor R
EN
should be chosen in the range from
2.2k
to 180K
. Recommended values for R
EN
and
C
EN
are respectively 100K
and 5.6nF. More infor-
mation on selecting the values is found in the Over-
current Protection section.
