Integrated bootstrap diode

A bootstrap circuitry is required to supply the high-voltage section.

This function is normally accomplished by an external high-voltage fast-

Shutdown function (SD)

The shutdown/open drain is an input/output pin. It can be used both as input

microcontroller for a rapid shutdown, and as an output from the IPM to ackno

a fault condition has been detected by the internal comparator.

When the voltage on pin SD drops below the lower threshold voltage, the IPM

to low level.

The maximum disable time (delay time from SD to the IGBT gates once the f

detected) to put both gates of a leg in low logic state is 200 ns.

Integrated op-amps

The integrated operational amplifiers are absolutely uncommitted, so a largeamplifier configurations can be implemented by an application designer.

Many types of motor control (including vector control, field-oriented control) phase currents to perform their algorithms. With the IPM, these can be imple

Interlocking function

The interlock function is an integrated protection that avoids cross-conductio

due to overlapped input signals.
