CIRCUIT DESCRIPTION
POWER STAGES and CHARGE PUMP
The L6205 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.

LOGIC INPUTS
Pins IN1
A
, IN2
A
, IN1
B
and IN2
B
are TTL/CMOS and
μ
C compatible logic inputs. The internal structure is
shown in Fig. 4. Typical value for turn-on and turn-off
thresholds
are
respectively
Vthoff=1.3V.
Pins EN
A
and EN
B
have identical input structure with
the exception that the drains of the Overcurrent and
thermal protection MOSFETs (one for the Bridge A
and one for the Bridge B) are also connected to these
pins. Due to these connections some care needs to
be taken in driving these pins. The EN
A
and EN
B
in-
puts may be driven in one of two configurations as
shown in figures 5 or 6. If driven by an open drain
Vthon=1.8V
and
(collector) structure, a pull-up resistor R
EN
and a ca-
pacitor C
EN
are connected as shown in Fig. 5. If the
driver is a standard Push-Pull structure the resistor
R
EN
and the capacitor 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 information on selecting the values is found in
the Overcurrent Protection section.
