iC-RC1000
SIN/COS SIGNAL SAFETY MONITOR IC
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 input signals
(500 mV amplitude per line)
o Verification of common mode range per signal line
(from DC to 500 kHz)
o Lissajous figure monitoring with min/max limits
(from DC to 100 kHz)
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
