2.2 Pin Description

HIN(U, V, W) and LIN(U, V, W) (Low side and high
side control pins, Pin 7 - 12)

These pins are positive logic and they are
responsible for the control of the integrated IGBTs.
The schmitt-trigger input thresholds of them are
such to guarantee LSTTL and CMOS compatibility
down to 3.3 V controller outputs. Pull-down resistor
of about 5 k is internally provided to pre-bias
inputs during supply start-up. 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

FIL,IN

. The filter acts according to

Figure 4.

It is not recommended for proper work to provide
input pulse-width lower than 1 µs.

The integrated gate driver provides additionally a
shoot through prevention capability which avoids
the simultaneous on-state of two gate drivers of the
same leg (i.e. HO1 and LO1, HO2 and LO2, HO3 and
LO3). When two inputs of a same leg are activated,
only former activated one is activated so that the leg
is kept steadily in a safe state.

A minimum deadtime insertion of typically 360 ns is
also provided by driver IC, in order to reduce cross­conduction of the external power switches.

RFE (Fault / Fault clear time / Enable, Pin 14)

The RFE pin conbines three functions in one pin:
programmable fault clear time by RC-network, fault­out and enable input.

The programmable fault-clear time can be adjusted
by RC network, which is external pull-up resistor and
capacitor. For example, typical value is about 1ms at

1 MΩand 2 nF.

The fault-out indicates a module failure in case of
under voltage at pin VDD or in case of triggered over
current detection at ITRIP.

The microcontroller can pull this pin low to disable
the IPM functionality. This is enable function.

VTH (Thermistor, Pin 17)

The VTH pin provides direct access to the NTC,
which is referenced to VSS. An external pull-up
resistor connected to +5 V ensures that the resulting
voltage can be directly connected to the
microcontroller.

ITRIP (Over current detection function, Pin 15)

IM818 provides an over current detection function
by connecting the ITRIP input with the IGBT
collector current feedback. The ITRIP comparator
threshold (typ. 0.5 V) is referenced to VSS ground. An
input noise filter (t

ITRIP

= typ. 500 ns) prevents the

driver to detect false over-current events.

Over current detection generates a shutdown of all
outputs of the gate driver after the shutdown
propagation delay of typically 1µs.

Fault-clear time is set to typical 1.1ms at R

RCIN

VDD, VSS (Low side control supply and
reference, Pin 13, 16)

VDD is the control supply and it provides power both
to input logic and to output power stage. Input logic
is referenced to VSS 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+

= 12.2 V is present.

The IC shuts down all the gate drivers power outputs,
when the VDD supply voltage is below V

DDUV-

= 11.2 V.
This prevents the external power switches from
critically low gate voltage levels during on-state and
therefore from excessive power dissipation.

VB(U, V, W) and VS(U, V, W) (High side supplies,
Pin 1 - 6)

VB to VS is the high side supply voltage. The high side
circuit can float with respect to VSS 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+

= 11.2 V and a

falling threshold of V

BSUV-

= 10.2 V.

VS(U, V, W) provide a high robustness against
negative voltage in respect of VSS of -50 V transiently.
This ensures very stable designs even under rough
conditions.

NW, NV, NU (Low side emitter, Pin 18 - 20)

The low side emitters are available for current
measurements of each phase leg. It is
recommended to keep the connection to pin VSS as
short as possible in order to avoid unnecessary
inductive voltage drops.

W, V, U (High side emitter and low side collector,
Pin 21 - 23)

These pins are motor U, V, W input pins.

P (Positive bus input voltage, Pin 24)

The high side IGBTs are connected to the bus
voltage. It is noted that the bus voltage does not
exceed 900 V.
