ZSC31150GAB

Overview

The ZSC31150GAB is a sensor interface component from the Renesas Electronics ZSC31150 series, designed for amplification and sensor-specific correction of bridge sensor signals. It is manufactured as an unwafer die intended for surface mount device (SMD/SMT) installation. The device accommodates nearly all resistive bridge sensors by utilizing a programmable gain amplifier (PGA) and a programmable analog-to-digital converter (ADC). It provides digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity via an internal 16-bit RISC microcontroller. The unit weight is 121.800 mg, and it is supplied in a gel pack configuration with a factory packaging quantity of 2800 units.

Feature Summary

• Provides digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity using an integrated 16-bit RISC microcontroller.
• Accommodates virtually any resistive bridge sensor through a programmable gain amplifier and programmable ADC.
• Supports bi-directional digital interfaces including I2C and ZACwire for calibration coefficient programming into on-chip EEPROM.
• Optimized for automotive environments with protection circuitry and excellent electromagnetic compatibility.

Applications

• Automotive pressure sensors, including piezoresistive and steel-membrane-based types.
• Force, torque, acceleration, angle, position, and revolution sensors.
• Safety-critical systems such as braking or steering applications requiring diagnostic functions.

Procurement Notes

Verify the specific package type and handling requirements for the unwafer die configuration before integration. Confirm that the gel pack packaging meets your cleanroom standards. Ensure the ordering suffix matches the exact die specification required for your application. Cross-reference the datasheet for any recent product change notifications. Validate compatibility with your assembly process for bare die attachment.

Selection Notes

Select this part when a bare die solution is preferred over packaged ICs for space-constrained automotive designs. Consider the ZSC31150GAG2-R if a pre-packaged SSOP-14 option is needed instead of a die. Evaluate the ZSC31150GED if wafer-sawn dice are acceptable. Ensure the design supports the necessary calibration procedures via I2C or ZACwire interfaces. Verify thermal management capabilities for the target operating temperature range.

Part Context

The ZSC31150GAB belongs to the broader ZSC31150 family of fast automotive sensor signal conditioners. This series includes various packaging options such as DFN-14, SSOP-14, and different die configurations like GAB, GED, and GLG1. All variants share the core functionality of conditioning bridge sensor signals for automotive safety applications. The GAB suffix specifically denotes the unwafer die format within this product line.
