Pin Description

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 stage. Input logic is

referenced to VSS ground.

The undervoltage circuit enables the device to

operate at power on when a supply voltage of at

least a typical voltage of VDDUV+ = 12.4 V is present.

The gate driver shuts down all the outputs, when

the VDD supply voltage is below VDDUV- = 11.5 V. This

prevents the IGBTs 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 high-side IGBT emitter voltage.

Due to the low power consumption, the floating

driver stage is supplied by integrated bootstrap

circuit.

The undervoltage detection operates with a rising

supply threshold of typical VBSUV+ = 11.5 V and a

falling threshold of VBSUV- = 10.7 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 harsh

conditions.

NW, NV, NU (Low-side emitter, Pin 17 - 19)

The low-side emitters are available for current

measurement of each phase leg. It is recommended

to keep the connection to pin VSS as short as

possible to avoid unnecessary inductive voltage

drops.

W, V, U (High-side emitter and low-side collector,

Pin 20 - 22)

These pins are connected to motor U, V, W input

pins

P (Positive bus input voltage, Pin 23)

The high-side IGBTs are connected to the bus

voltage. It is noted that the bus voltage does not

exceed 450 V.
