Renesas Electronics RAA3064002GFP Resolver-to-Digital Converter

Renesas Electronics RAA3064002GFP#AA0 Resolver-to-Digital Converter is designed to convert signals (electrical angle information) detected by the resolver sensor (angle sensor) a digital signal. This converter is intended for use with single-phase excitation, two-phase output type resolver sensors. These sensor outputs analog signals are directly proportional to the angle of the mechanical rotation of the resolver. The RAA3064002GFP#AA0 IC can be connected to either of the two types of resolver sensors i.e transformer type or current detection type. This IC incorporates amplifiers that are configured with noise filters to eliminate noise in the signals detected by the resolver sensor. The RAA3064002GFP#AA0 IC outputs a single-phase excitation signal to the resolver sensor that is triggered by the excitation clock signal input from the host MCU. This IC thus generates an angle signal to the host MCU to measure the difference between the rectangular excitation wave and angle signal.

This RAA3064002GFP#AA0 IC incorporates amplifiers that are configured with noise filters to eliminate noise in the signals detected by the resolver sensor. This IC includes a circuit to correct errors in the detected signal from the resolver. The RAA3064002GFP#AA0 IC features the functionality of detecting an excessive temperature within the chip and has two shunt current amplifiers for use in general motor circuits. This IC is used in applications using motors that require a high-resolution angle, excluding those for automotive use.
