Datasheet - production data
The L6390 is a full featured high voltage device
manufactured with the BCD ™ “offline”
technology. It is a single-chip half-bridge gate
driver for N-channel power MOSFETs or IGBTs.
The high-side (floating) section is able to work
with voltage rail up to 600 V.
Both device outputs can sink and source 430 mA
and 290 mA respectively. Prevention from cross
conduction is ensured by interlocking and
programmable deadtime functions.
The device has dedicated input pins for each
output and a shutdown pin. The logic inputs are
CMOS/TTL compatible down to 3.3 V for easy
interfacing with control devices. Matched delays
between low-side and high-side sections
guarantee no cycle distortion and allow high
The L6390 embeds an operational amplifier
suitable for advanced current sensing in
applications such as field oriented motor control
or for sensorless BEMF detection. A comparator
featuring advanced smartSD function is also
integrated in the device, ensuring fast and
effective protection against fault events like
overcurrent, overtemperature, etc.
The L6390 device features also UVLO protection
on both the lower and upper driving sections,
preventing the power switches from operating in
low efficiency or dangerous conditions.
The integrated bootstrap diode as well as all of
the integrated features of this IC make the
application PCB design easier, more compact and
simple thus reducing the overall bill of material.
The device is available in an SO-16 tube and tape
and reel packaging options.
