Description
The L6393 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 are CMOS/TTL compatible down
to 3.3 V for easy interfacing microcontroller/DSP.
The IC embeds an uncommitted comparator
available for protections against overcurrent,
overtemperature, etc.

2 Pin connection
Figure 2. Pin connection (top view)
Table 2. Pin description The circuit provides less than 1 V on the LVG and HVG pins (@ Isink = 10 mA), with VCC > 3 V. This
allows omitting 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.
L6393 Truth table

3 Truth table
Note: X: don’t care
In the L6393 IC the two input signals PHASE and BRAKE are fed into an AND logic port and
the resulting signal is in phase with the high side output HVG and in opposition of phase with
the low side output LVG. This means that if BRAKE is kept to high level, the PHASE signal
drives the half-bridge in phase with the HVG output and in opposition of phase with the LVG
output. If BRAKE is set to low level the low side output LVG is always ON and the high side
output HVG is always OFF , whatever the PHASE signal. This kind of logic interface provides
the possibility to control the power stages using the PHASE signal to select the current
direction in the bridge and the BRAKE signal to perform current slow decay on the low sides.
From the point of view of the logic operations the two signals PHASE and BRAKE are
completely equivalent, that means the two signals can be exchanged without any change in
the behavior on the resulting output signals (see the Figure 1 on page 3).
Note: The dead time between the turn OFF of one power switch and the turn ON of the other
power switch is defined by the resistor connected between DT pin and the ground.
