Description
The L6391 is a high-voltage device manufactured
with the BCD “OFF-LINE” technology. It is a single
chip half-bridge gate driver for N-channel power
MOSFET or IGBT.
The high side (floating) section is designed to
stand a voltage rail up to 600 V. The logic inputs
arewww.DataSheet.net/ CMOS/TTL compatible down to 3.3 V for easy
interfacing microcontroller/DSP.
An integrated comparator is available for
protections against overcurrent, overtemperature,
etc.

1. VBO = Vboot - Vout
2. RDSON is tested in the following way:
RDSON = [(VCC - VCBOOT1) - (VCC - VCBOOT2)] / [I1(VCC,VCBOOT1) - I2(VCC,VCBOOT2)]
where I1 is pin 14 current when VCBOOT = VCBOOT1, I2 when VCBOOT = VCBOOT2.
