Pin Configuration

Pin Descriptions
The IC shuts down all the gate drivers power
outputs, when the V
DD
supply voltage is below V
DDUV-
= 10.9V. This prevents the external power switches
from critically low gate voltage levels during on-
state and therefore from excessive power
dissipation.
V
B(1,2,3)
and V
S(1,2,3)
(High side supplies)
V
B
to V
S
is the high side supply voltage. The high side
circuit can float with respect to COM following the
external high side power device emitter voltage.
Due to the low power consumption, the floating
driver stage is supplied by integrated bootstrap
circuit.
The under-voltage detection operates with a rising
supply threshold of typical V
BSUV+
= 11.1V and a falling
threshold of V
BSUV-
= 10.9V.
V
S(1,2,3)
provide a high robustness against negative
voltage in respect of COM. This ensures very stable
designs even under rough conditions.
V

(Low side emitters)

FILIN
HIN(1,2,3) and LIN(1,2,3) (Low side and high side
control pins)
These pins are positive logic and they are
responsible for the control of the integrated IGBT.
The Schmitt-trigger input thresholds of them are
such to guarantee LSTTL and CMOS compatibility
down to 3.3V controller outputs. Pull-down resistor
of about 800k is internally provided to pre-bias
inputs during supply start-up and an ESD diode is
provided for pin protection purposes. Input
Schmitt-trigger and noise filter provide beneficial
noise rejection to short input pulses.
The noise filter suppresses control pulses which are
below the filter time
T
FILIN
. The filter acts according
to Figure 4.

The low side emitters are available for current
measurements of each phase leg. It is
recommended to keep the connection to pin COM as
short as possible in order to avoid unnecessary
inductive voltage drops.
VTH (Thermistor output)
A UL certified NTC resistor is integrated in the
module with one terminal of the chip connected to
COM and the other to VTH. When pulled up to a rail
voltage such as V
DD
or 3.3V by a resistor, the VTH pin
provides an analog voltage signal corresponding to
the temperature of the thermistor.
RFE (RCIN / Fault / Enable)
The RFE pin combines 3 functions in one pin: RCIN or
RC-network based programmable fault clear timer,
fault output and enable input.
The RFE pin is normally connected to an RC network
on the PCB per the schematic in Figure 5. Under
normal operating conditions, R
RCIN
pulls the RFE pin
to 3.3V, thus enabling all the functions in the IPM.
The microcontroller can pull this pin low to disable
the IPM functionality. This is is the Enable function.

The integrated gate drive provides additionally a
shoot through prevention capability which avoids
the simultaneous on-state of the high-side and low-
side switch of the same inverter phase. A minimum
deadtime insertion of typically 300ns is also
provided by driver IC, in order to reduce cross-
conduction of the external power switches.
V
DD
, COM (Low side control supply and reference)
V
DD
is the control supply and it provides power both
to input logic and to the output power stage. Input
logic is referenced to COM ground.
The under-voltage circuit enables the device to
operate at power on when a supply voltage of at
least a typical voltage of V
DDUV+
= 11.1V is present.
