Power Connections
can be obtained from the package outline in Figure 8 and circuit
diagram in Figure 9. Three phase input connections made to pins
R, S and T and inverter output connections are made to pins U, V
and W. Positive rectifier output and positive inverter bus are
brought out to pins RP and P respectively in order to provide DC
bus capacitor soft charging implementation option. The current
shunt terminals are connected to pins IS1, IS2 and IS3, IS4 on
the positive and negative DC rails respectively.

Heat Sink Requirements
required for various output power levels and Pulse-Width-
Modulated (PWM) switching frequencies. Maximum total losses
of the unit are also shown. This data is based on the following
key operating conditions:
Over Temperature Protection

circuit that initiates a shutdown if the temperature of the IMS
substrate exceeds a set level can be implemented. The nominal
resistance vs. temperature characteristic of the thermistor is
given in Figure 6.
Voltage Rise During Braking
regenerative braking, forcing the DC bus voltage to rise above
the level defined by the input line voltage. Deceleration of the
motor must be controlled by appropriate PWM control to keep
the DC bus voltage within the rated maximum value.
