ZSC31150GLG1-R

Overview

The ZSC31150GLG1-R is a CMOS integrated circuit designed as an automotive sensor signal conditioner. It provides digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity using a 16-bit RISC microcontroller. The device accommodates resistive bridge sensors with programmable gain amplifiers and ADCs. It operates on a supply voltage of 4.5V to 5.5V with a maximum current consumption of 5.5mA. The component supports output via voltage (0 to 5V), I2C, or ZACwire interfaces. It features adjustable ADC resolution from 13 to 16 bits and a sampling rate up to 7.8kHz. The unit is housed in an SSOP-14 package and is qualified under AEC-Q100 standards.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
• Accommodates nearly all bridge sensors by PGA and programmable ADC
• Set of diagnostics functions needed for safety applications
• Output options include voltage, I2C, and ZACwire one-wire interface

Applications

• Automotive pressure sensors
• Braking systems
• Steering systems

Procurement Notes

Verify the specific suffix GLG1-R against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm availability status directly with authorized distributors, as this variant may have limited stock or end-of-life implications. Ensure the ordering quantity matches the required packaging format, such as cut tape or reel, to avoid handling errors during assembly.

Selection Notes

Select this component when digital correction of bridge sensor signals is required for automotive safety applications. It is suitable for environments requiring operation between -40°C and +125°C or +150°C. Choose this part if I2C or ZACwire communication is preferred over analog-only outputs. Verify that the SSOP-14 package fits the PCB layout constraints and that the 5V supply rail aligns with the system design.

Part Context

The ZSC31150 series is optimized for automotive environments, offering protection circuitry and electromagnetic compatibility. It is specifically suited for most pressure sensors but can also be used with force, torque, acceleration, angle, position, and revolution sensors. The device allows calibration coefficients to be written into on-chip EEPROM via bi-directional digital interfaces.
