Overview
Sensor Signal Conditioner for Safety Switch Applications ZSSC3136 Datasheet Brief Description The ZSSC3136 is a member of the ZSSC313x family of CMOS integrated circuits for automotive/ industrial sensor applications.
All family members are well suited for highly accurate amplification and sensor-specific correction of resistive bridge sensor signals.
An internal 16-bit RISC microcontroller running a correction algorithm compensates sensor offset, sensitivity, temperature drift, and non-linearity of the connected sensor element.
The required calibration coefficients are stored by the one-pass calibration procedure in an on-chip EEPROM.
The ZSSC3136 is optimized for SIL (Safety Integrity Level) rated switch applications.
The integrated adjustable digital filter offers the possibility of setting up fast switching real-time applications as well as stabilized switching applications in the case of disturbed or unstable input signals.
In addition to the general features for switch applications, the ZSSC3136 offers the capability to set up safety-relevant SIL2 rated switches due to its extended safety functionalities.
