TSC2013QPWRQ1

Overview

The TSC2013QPWRQ1 is an automotive-grade, four-wire resistive touchscreen controller manufactured by Texas Instruments. It features a 12-bit resolution with selectable 10-bit mode and operates on a single supply voltage ranging from 1.2V to 3.6V. The device integrates an I²C interface for communication and consumes only 655 µA of supply current. Designed for harsh environments, it supports an operating temperature range from -40°C to +125°C and is housed in a 16-pin TSSOP package. The component meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• 12-bit resolution with 10-bit option for resistive touch input
• I²C serial interface compatible with standard protocols
• Ultra-low power consumption of 655 µA at 1.8V
• AEC-Q100 qualified for automotive reliability

Applications

• Automotive infotainment systems requiring resistive touch input
• Industrial control panels with wide temperature requirements
• Portable electronic devices utilizing low-voltage operation

Procurement Notes

Verify the specific suffix 'PWR' confirms the 16-TSSOP package and automotive grade (Q1) designation. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to PCB assembly planning. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Selection Notes

Select this component when a resistive touchscreen interface is required in automotive or industrial settings. The 1.2V to 3.6V supply range allows compatibility with various logic levels. The I²C interface reduces pin count compared to SPI alternatives. Verify that the 655 µA current draw fits within the system's power budget constraints.

Part Context

This part belongs to the TSC2013-Q1 family of touchscreen controllers. It shares core functionality with variants like the TSC2013QRSARQ1 but differs in packaging. The Q1 suffix indicates automotive qualification, distinguishing it from commercial grade counterparts. It serves as a dedicated interface between resistive touch panels and host processors.

Replacement Considerations

Direct substitutes include other TSC2013 variants such as TSC2013QRSARQ1 if package differences are acceptable. Cross-reference with ADS7843 series for similar functionality, though interface and pinouts may differ. Verify electrical parameters and package dimensions before substituting.
