TPIC83000IPWRQ1

Overview

The TPIC83000IPWRQ1 is a single-channel signal conditioning device for pressure sensors, designed for low-pressure sensing applications in automotive environments. It features a 14-bit sigma-delta ADC with 10-bit effective resolution and a built-in 12-bit ADC for ambient temperature compensation. The device includes an on-board EEPROM for system calibration data storage and supports programmable gain and offset adjustments. Communication with the microcontroller is handled via a UART interface operating at configurable baud rates. It operates within a temperature range of –40°C to 85°C and is housed in a 16-pin TSSOP package.

Feature Summary

• Integrated analog front-end with programmable gain and offset correction for strain gauge or piezo-resistive sensors
• Built-in 12-bit temperature sensor for thermal compensation of sensor output
• On-board EEPROM for storing calibration parameters and system configuration data
• UART communication interface with support for multiple addressing modes and diagnostic reporting

Applications

• Occupancy weight sensing
• Pedal-pressure sensing
• General low-pressure sensing

Procurement Notes

Verify the specific ordering suffix IPWRQ1 corresponds to the TSSOP-16 package and automotive qualification requirements. Confirm that the reel quantity matches the standard packaging specification of 2000 units per reel. Ensure compatibility with the required 5V supply voltage and UART logic levels for the target microcontroller interface.

Selection Notes

Select this component when a single-channel signal conditioning solution is needed for low-pressure automotive sensors. Consider the 10-bit output resolution and UART interface requirements against the processing capabilities of the host microcontroller. Evaluate the need for internal temperature compensation and EEPROM-based calibration storage for the specific application environment.
