The PGA411-Q1 is capable of simultaneously exciting the resolver sensor coil and calculating the angle and velocity of a rotating motor shaft without the use of external components and is intended for application in automotive and industrial applications.

It is also the first resolver sensor interface with integrated power supply, exciter amplifier and functional safety features, which allow it to support a range of 4Vrms and 7Vrms resolver sensors.

Integrated built-in self-test (BIST) performs an analog and logic component self-check automatically upon startup supporting, Automotive Safety Integrity Level (ASIL) D functional safety certification for the ISO26262 standard.
