Description
The L6388E is a high voltage gate driver,
manufactured with the BCD ™ “offline”
technology, and able to drive a half-bridge of
power MOSFET/IGBT devices. The high-side
(floating) section is enabled to work with voltage
rail up to 600 V. Both device outputs can sink and
source 650 mA and 400 mA respectively and
cannot be simultaneously driven high thanks to an
integrated interlocking function. Further
prevention from outputs cross conduction is
guaranteed by the deadtime function.
The L6388E device has two input and two output
pins, and guarantees the outputs switch in phase
with inputs. The logic inputs are CMOS/TTL
compatible (3.3 V, 5 V and 15 V) to ease the
interfacing with controlling devices.
The bootstrap diode is integrated in the driver
allowing a more compact and reliable solution.
The L6388E device features the UVLO protection
on both supply voltages (V
CC
and V
BOOT
)
ensuring greater protection against voltage drops
on the supply lines.
The device is available in a DIP-8 tube and SO-8
tube, and tape and reel packaging options.
