L6386ED Datasheet PDF - ST Microelectronics

The L6386ED is a high voltage low-side Gate Driver with BCD™ offline technology and able to drive simultaneously one high and one low-side power MOS or IGBT device. The high-side (floating) section is enabled to work with voltage rail up to 600V. Both device outputs can independently sink and source 650 and 400mA respectively and can be simultaneously driven high. The 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. This integrates a comparator that can be used to protect the device against fault events, like the over-current. 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.

● CMOS/TTL Schmitt trigger inputs with hysteresis and pull-down

● Under-voltage lockout on lower and upper driving section

● Integrated bootstrap diode

● Outputs in phase with inputs
