ZSSC4175BE3R

Overview

The ZSSC4175BE3R is a sensor signal conditioner integrated circuit designed for dual voltage source sensors, specifically supporting N-type thermocouples. It operates within a supply voltage range of 4.75V to 5.25V and functions across an operating temperature range of -40°C to +150°C. The device provides digital compensation for offset, gain, nonlinearity, and temperature drift using an internal microcontroller. It features SENT or I2C output interfaces and supports OWI calibration via the data pin. The component is housed in a 4x4mm QFN-24 package.

Feature Summary

• Dual voltage source sensor interface with support for N-type thermocouples
• Digital compensation for offset, sensitivity, higher-order nonlinearity, and temperature coefficients
• SENT output option compliant with SAE J2716 Rev 3.0 standard
• Integrated non-volatile memory for configuration and calibration data storage

Applications

• Automotive pressure sensors
• Thermocouple temperature measurement modules
• Strain gauge signal conditioning
• NTC/PTC RTD temperature sensing systems

Procurement Notes

Verify current availability status directly with Renesas Electronics Corporation or authorized distributors, as lead times and stock levels fluctuate. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with automotive functional safety standards relevant to your application environment before finalizing procurement decisions.

Selection Notes

Select this model when dual-channel thermocouple input is required alongside SENT communication capabilities. Verify compatibility with N-type thermocouple specifications. Consider the QFN-24 package constraints for PCB layout. Evaluate if the internal cold-junction compensation meets system accuracy requirements without external sensors.
