TSC2046EIPW

Overview

The TSC2046EIPW is a resistive touch screen controller manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It features a 12-bit resolution and supports SPI interface communication. The device operates within a supply voltage range of 2.2V to 5.25V and functions across a temperature range of -40°C to +85°C. Key electrical parameters include a maximum sampling rate of 125 kS/s and a typical operating current of 280 µA. The component integrates an internal voltage reference and is designed for surface-mount installation.

Feature Summary

12-bit ADC resolution for precise coordinate detection
SPI serial interface with 3-wire or 4-wire compatibility
Integrated internal voltage reference
Low power consumption with 280 µA operating current

Applications

Resistive touch screen controllers
Industrial HMI interfaces
Portable measurement devices

Procurement Notes

Verify the specific suffix 'IPW' corresponds to the TSSOP-16 package variant. Confirm RoHS compliance status as indicated in distributor documentation. Check for end-of-life notices, as some sources indicate obsolescence phases for this series. Ensure the ordering quantity matches the tube packaging specifications provided by the manufacturer.

Selection Notes

Select the TSC2046EIPW when a 12-bit resolution and SPI interface are required for resistive touch applications. Compare against the TSC2046EIRGVT if a VQFN package is preferred for space-constrained designs. Verify that the 2.2V to 5.25V supply range aligns with the system's power architecture. Consider the 125 kS/s sampling rate for real-time coordinate tracking requirements.

Part Context

This component belongs to the TSC2046 family of touch screen controllers from Texas Instruments. It serves as a dedicated solution for converting analog signals from resistive touch panels into digital coordinates via an integrated SAR ADC. The IPW suffix denotes the specific plastic TSSOP package type used for surface mounting.
