ZSSC3136BE2T

Overview

The ZSSC3136BE2T is an automotive-grade sensor signal conditioner from the ZSSC313x family, designed for safety switch applications. It features a 16-bit RISC microcontroller and analog frontend for resistive bridge sensors. Key electrical parameters include a supply voltage range of 4.5 V to 5.5 V, maximum supply current of 5.5 mA, and operation temperature from -40°C to +125°C (up to +150°C per datasheet). It offers 12.4-bit resolution analog output or ZACwire digital interface, high voltage protection up to 33V, and ESD protection. The device is AEC-Q100 qualified and housed in an SSOP-14 package.

Feature Summary

• Internal 16-bit RISC microcontroller compensates for sensor offset, sensitivity, temperature drift, and non-linearity via single-pass calibration stored in on-chip EEPROM.
• Adjustable digital filter supports both fast switching real-time applications and stabilized switching for disturbed input signals.
• Provides ratiometric analog voltage output or ZACwire digital one-wire interface with high voltage protection up to 33V.

Applications

• Safety Integrity Level (SIL) rated switch applications
• Automotive sensor interfaces requiring digital compensation
• Resistive bridge sensor signal conditioning

Procurement Notes

Verify the specific suffix 'BE2T' against the manufacturer's official datasheet to confirm tape-and-reel packaging and exact temperature grade. Ensure the part number matches the intended SIL rating requirements. Cross-reference with Renesas Electronics documentation to confirm availability and lead times before procurement.

Selection Notes

Select this component when digital compensation for resistive bridge sensors is required in automotive environments. It is suitable for designs needing SIL-rated functionality with integrated microcontroller capabilities. Consider the 12.4-bit resolution and I2C interface compatibility for system integration.

Part Context

The ZSSC3136BE2T belongs to the ZSSC313x product family of CMOS integrated circuits. This family is optimized for highly accurate amplification and sensor-specific correction of resistive bridge sensor signals in automotive and industrial applications.

Replacement Considerations

Check for other members of the ZSSC313x family, such as ZSSC3135 or ZSSC3138, which may offer similar signal conditioning but potentially different gain stages or interface options. Verify pinout and software compatibility if substituting within the same series.
