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
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.
