ZSC31150GLG1-T

Overview

The ZSC31150GLG1-T is a fast automotive sensor signal conditioner manufactured by Renesas Electronics. It functions as a CMOS integrated circuit designed for the amplification and sensor-specific correction of bridge sensor signals. The device incorporates digital compensation for offset, sensitivity, temperature drift, and non-linearity via an internal 16-bit RISC microcontroller. It accommodates resistive bridge sensors with input ranges from 1mV/V to 275mV/V. Key electrical parameters include a supply voltage range of 4.5 V to 5.5 V, a maximum operating current of 5.5 mA, and an output current capability of 5 mA. The component operates within a temperature range of -40°C to +150°C and utilizes an SSOP-14 package.

Feature Summary

• Provides digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity using an internal microcontroller algorithm.
• Supports multiple output options including analog voltage (0 to 5V), I2C, and ZACwire one-wire interface.
• Features adjustable ADC resolution ranging from 13 to 16 bits with sampling rates up to 7.8kHz.
• Includes diagnostic functions suitable for safety-critical automotive applications such as braking or steering systems.

Applications

• Pressure sensors in automotive environments
• Force, torque, and acceleration sensors
• Angle, position, and revolution sensors

Procurement Notes

Verify the specific suffix GLG1-T against the manufacturer's latest documentation to confirm package type and tape-and-reel configuration. Check for End-of-Life status or discontinuance notifications, as availability may be restricted. Ensure compatibility with AEC-Q100 qualification requirements if used in automotive designs. Confirm that the SSOP-14 footprint matches the target PCB layout constraints.

Selection Notes

Select this component when digital calibration of bridge sensors is required to eliminate external trimming components. Consider the ZSC31150GLG1-T for designs needing high accuracy without complex external processing. Evaluate the I2C and ZACwire interfaces for system integration complexity. Verify that the 150°C maximum junction temperature meets the thermal environment of the intended application.
