DescriptionThe L6386AD is a high voltage gate driver,
manufactured with the BCD™ “offline”
technology, and able to drive simultaneously one
high and one low-side power MOS or IGBT
device. The high-side (floating) section is enabled
to work with voltage rail up to 600 V. Both device
outputs can independently sink and source
650 mA and 400 mA respectively and can be
simultaneously driven high.
The L6386AD device provides two input pins, two
output pins and an enable pin (SD), and
guarantees the outputs switch in phase with
inputs. The logic inputs are CMOS/TTL
compatible to ease the interfacing with controlling
devices.
The L6386AD integrates a comparator (inverting
input internally referenced to 0.5 V) that can be
used to protect the device against fault events,
like overcurrent. The DIAG output is a diagnostic
pin, driven by the comparator, and used to signal
a fault event occurrence to the controlling device.
The bootstrap diode is integrated in the driver
allowing a more compact and reliable solution.
The L6386AD device features the UVLO
protection on both supply voltages (VCC and
Vboot) ensuring greater protection against voltage
drops on the supply lines.
The device is available in a SO-14 package, in
tube, and tape and reel packaging.

2.4 Pin connection
Figure 2. Pin connection (top view)
Table 5. Pin description The circuit guarantees 0.3 V maximum on the pin (at Isink = 10 mA), with VCC > 3 V. This allows to omit the “bleeder” resistor connected between the gate and the source of the external MOSFET normally used to hold the pin low; the gate driver assures low impedance also in SD condition.

4 Bootstrap driver
A bootstrap circuitry is needed to supply the high voltage section. This function is normally
accomplished by a high voltage fast recovery diode (Figure 4 a). In the L6386AD device
a patented integrated structure replaces the external diode. It is realized by a high voltage
DMOS, driven synchronously with the low-side driver (LVG), with a diode in series, as
shown in Figure 4 b. An internal charge pump (Figure 4 b) provides the DMOS driving
voltage. The diode connected in series to the DMOS has been added to avoid undesirable
turn-on.
