Description

The 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 MOSFET or IGBT

device. The high-side (floating) section is able 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 in order to drive

asymmetrical half-bridge configurations.

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 (V

and

BOOT

) 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.

Bootstrap driver 4 L6386AD 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.

L6386AD Bootstrap driver For example: using a power MOSFET with a total gate charge of 30 nC, the drop on the bootstrap DMOS is about 1 V, if the Tcharge is 5 ms. In fact: Equation 3 30nC V drop = ---------------  125  0.8V 5s Vdrop has to be taken into account when the voltage drop on CBOOT is calculated: if this drop is too high, or the circuit topology doesn’t allow a sufficient charging time, an external diode can be used.
