Halt Logic Signal (HLS)
The Halt Logic Signals PRIM_HALT_IN and PRIM_HALT_OUT show and control the drive core status. The driver core is
placed into halt mode by setting PRIM_HALT_IN into HIGH state (disable driver). This signal can gather disable signals of
other hardware components for stopping operation and switching off the IGBT. A HIGH signal will set the driver core into
HOLD and switching pulses from the controller will be not transferred to the output stage. The input and output have Schmitt
Trigger characteristic. Pull up and open collector output stages must not be used.
Please note:
PRIM_HALT_OUT must be always connected with PRIM_HALT_IN. PRIM_HALT_OUT is not short circuit proof.
Connection PRIM_HALT_OUT and PRIM_HALT_IN
Connection PRIM_HALT_OUT (PRIM_HALT_IN not used)
Please note:
A HIGH signal @ PRIM_HALT_IN does not generate a HIGH signal @ PRIM_HALT_OUT. After LOW signal @ PRIM_HALT_IN the
gate driver is enable do operate.
Dead Time generation (Interlock TOP / BOT) adjustable (DT)
The DT circuit prevents, that TOP and BOT IGBT of one half bridge are switched on at the same time (shoot through). The
dead time is not added to a dead time given by the controller. Thus the total dead time is the maximum of "built in dead time"
and "controller dead time". It is possible to control the driver with one switching signal and its inverted signal.
Pulse pattern – DT
ƒ The total propagation delay of the driver is the sum of interlock
dead time (tTD) and driver input output signal propagation delay
(td(on;off)IO) as shown in the pulse pattern. Moreover the switching
time of the IGBT chip has to be taken into account (not shown in
the pulse pattern).
ƒ In case both channel inputs (PRIM_TOP_IN and
PRIM_BOT_IN) are at high level, the IGBTs will be turned off.
ƒ If only one channel is switching, there will be no interlock dead
time.
Please note:
No error message will be generated when overlap of switching signals occurs.
The dead time can be adjusted and the locking function may be neutralized as shown in the following table.
