ZSSC4175BE2R

Overview

The ZSSC4175BE2R is a dual-channel sensor signal conditioner IC from the ZSSC416x/ZSSC417x family, designed for high-accuracy amplification and correction of differential voltage source sensor signals. It features a configurable analog-to-digital converter with resolution ranging from 12 to 16 bits and supports SENT or I²C digital output interfaces. The device operates on a supply voltage between 4.75V and 5.25V, withstands overvoltage up to +/-18V, and maintains an accuracy of ±0.25% FSO within the -40°C to 125°C range. It utilizes a 16-bit RISC microcontroller for digital compensation of offset, gain, nonlinearity, and temperature drift.

Feature Summary

• Dual voltage source sensor inputs supporting N-type thermocouples
• Digital compensation for offset, gain, higher-order nonlinearity, and temperature coefficients
• Configurable ADC resolution from 12 to 16 bits with internal or external temperature sensing options
• SENT interface compliant with SAE J2716 Rev 3.0 standard

Applications

• Dual thermocouple temperature measurement systems
• Automotive pressure sensors requiring extended temperature diagnostics
• Strain gauge and resistive bridge sensor conditioning
• NTC/PTC RTD temperature sensing modules

Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm package integrity upon receipt as the unit is supplied in QFN24 format. Check manufacturing date codes against current production status to ensure compatibility with long-term supply requirements.

Selection Notes

Select this model specifically for applications requiring dual voltage source inputs such as thermocouples. Ensure system design accommodates the 4.75V to 5.25V supply range and utilizes the appropriate digital interface (SENT or I²C) for data transmission.

Part Context

This component belongs to the ZSSC416x/ZSSC417x sensor signal conditioner family originally developed by Integrated Device Technology (IDT), now part of Renesas Electronics. The BE2 suffix indicates the QFN24 package variant optimized for automotive environments with specific operating temperature ranges.

Replacement Considerations

ZSSC4175DE4R is the manufacturer-recommended replacement for the discontinued ZSSC4175BE2R. Verify pinout and software configuration compatibility before transitioning designs to the DE4R package variant.
