Resolver / Digital converters (Smartcoder)

Digital converters

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

– Adopts R/D conversion based on a proven digital tracking system

– Low cost, small size and light weight

– 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 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)
