Description
The L6392 is a high-voltage device, manufactured
with the BCD "OFF-LINE" technology. It has a
monolitich 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
are CMOS/TTL compatible down to 3.3 V for easy
of interfacing microcontroller/DSP
The IC embeds an op amp suitable for advanced
current sensing in applications such as field
oriented motor control.
