ZSC31150GEB

Overview

The ZSC31150GEB is a CMOS integrated circuit designed for the amplification and sensor-specific correction of bridge sensor signals. It functions as a single-channel sensor signal conditioner with an I2C interface, operating within a supply voltage range of 4.5 V to 5.5 V. The device features an internal reference type and provides analog output with a maximum output current of 5 mA. It supports an operating temperature range from -40°C to +150°C and includes ESD protection. The component is AEC-Q100 qualified for automotive applications and is housed in a DFN-14 package.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity via an on-chip microcontroller
• Accommodates nearly all resistive bridge sensors through programmable gain amplifier and ADC capabilities
• Integrated set of diagnostic functions supporting safety-critical automotive applications

Applications

• Pressure sensors in automotive braking or steering systems
• Force, torque, and acceleration sensing modules
• Angle, position, and revolution detection interfaces

Procurement Notes

Verify the exact suffix against manufacturer documentation to confirm package type and temperature grade. Confirm AEC-Q100 qualification status for automotive integration. Ensure compatibility with I2C bus requirements and check for specific ordering suffix variations that may affect pinout or thermal performance.

Selection Notes

Select this component when digital compensation for bridge sensors is required in harsh environments. The wide temperature range up to 150°C suits under-hood applications. Verify that the DFN-14 package fits the PCB layout constraints and that the I2C interface aligns with the system controller.

Part Context

This part belongs to the Renesas ZSC31150 series of sensor signal conditioners. The series offers configurable output options including voltage, I2C, and ZACwire. Variants within the family differ primarily by package style (SSOP-14, DFN-14) and operating temperature limits (-40°C to +125°C or +150°C).

Replacement Considerations

Check for direct substitutes within the ZSC31150 family such as ZSC31150GEG1 or ZSC31150GAG1. Verify if the alternative variant meets the specific temperature grade and package footprint requirements of the existing design.
