Smartcoder is a R/D (Resolver to Digital) conversion IC, which converts resolver signals into digital absolute position angle signals.
It is usable in a wide range of applications, including vehicle/robot/machine tool related applications, in combination with brushless resolvers such as our Smartsyn and Singlsyn.

Features of AU6805 Series

Satisfying fail check functions
Abnormality detection
Capable of detecting abnormal resolver signals, breaking of resolver signals, abnormal R/D conversion and abnormally high temperature of a IC
Built in self test
Conducts a self test on R/D conversion and abnormality detection
Realization of system/cost reduction based on all-in-one concepts
Integrated with an excttation amplifier (Output current: 1 OmA rms/20mA rms)
Integrated with an operation clock
Enhancement of functions corresponding to various applications
Requires no phase adjustment to excitation signals (Allowable range: Within土45゜）
Variable setting of controlling bandwidth (fBW) (Selectable from 7 types of fixed values or automatic adjustment)
Capable of digital conversion of linear hall IC signals and R/D parallel connections to resolvers
Output redundancy (Triple redundancy-Parallel/Pulse/Serial output)
