L6390
High-voltage high/low-side driver
Datasheet − production data
Description
The L6390 is a high-voltage device manufactured
with BCD™ “offline” technology. It is a single-chip
half bridge gate driver for N-channel Power
MOSFETs or IGBT.
The high-side (floating) section is designed to
stand a voltage rail up to 600 V. The logic inputs
are CMOS/TTL compatible down to 3.3 V for easy
microcontroller/DSP interfacing.
The IC embeds an operational amplifier suitable
for advanced current sensing in applications such
as field oriented motor control.
An integrated comparator is available for
protection against overcurrent, overtemperature,
etc.
■ Motor driver for home appliances, factory
automation, industrial drives
■ HID ballasts, power supply units

1. The circuit provides less than 1 V on the LVG and HVG pins (@ Isink = 10 mA), with VCC > 3 V. This allows
the omission of the “bleeder” resistor connected between the gate and the source of the external MOSFET
normally used to hold the pin low; the gate driver assures low impedance also in SD condition.
