Description
The L6384E is a high voltage gate driver,
manufactured with the BCD™ “offline”
technology, and able to drive a half-bridge of
power MOSFET or IGBT devices. The high-side
(floating) section is able 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
single input configuration. Further prevention
from outputs cross conduction is guaranteed by
the deadtime function, tunable by the user
through an external resistor connected to the
DT/SD pin.
The L6384E device has one input pin, one enable
pin (DT/SD) and two output pins, and guarantees
matched delays between low-side and high-side
sections, thus simplifying device's high frequency
operation. The logic inputs are CMOS/TTL
compatible to ease the interfacing with controlling
devices. The bootstrap diode is integrated inside
the device, allowing a more compact and reliable
solution.
The L6384E features the UVLO protection and
a voltage clamp on the V
CC
supply voltage. The
voltage clamp is typically around 15.6 V and is
useful in order to ensure a correct device
functioning in cases where V
CC
supply voltage is
ramped up too slowly or is subject to voltage
drops.
The device is available in a DIP-8 tube and SO-8
tube and tape and reel packaging options.
