preliminary
SIN/COS SIGNAL SAFETY MONITOR IC
Rev A2, Page 1/10
FEATURES
o Sine/cosine encoder signal monitoring for SIL applications
o Suitable for differential encoder signals of 1 Vpp
(250 mV amplitude per line)
o Suitable for single-ended signals (500 mV amplitude per line)
o Monitor for input frequencies from 0 to 500 kHz
o Verification of DC common mode range per signal line
o Monitoring of Lissajous curve with min/max limits
o Cable fracture detection
o Source decoupling and overvoltage clamping per pin by
external resistors
o Single-failure-proof dual channel concept
o Independent diagnostic outputs:
signal OK message and signal error message
APPLICATIONS
o Sensor monitoring
o Motion control
o Functional safety
