High voltage high and low side driver with bootstrap diode

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 VCCsupply voltage. The voltage clamp is typically around 15.6 V and is useful in order to ensure a correct device functioning in cases where VCCsupply 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.
