TSC2046IGQCR

Overview

The TSC2046IGQCR is a resistive touch screen controller manufactured by Texas Instruments, housed in a 48-VFBGA (Microstar Junior) package. It features a 12-bit successive approximation register ADC with a throughput rate of 125 kS/s. The device operates on a single supply voltage ranging from 2.2V to 5.25V and supports digital I/O levels from 1.5V to 5.25V. Key electrical characteristics include an internal 2.5V reference, QSPI/SPI 3-wire interface compatibility, and support for direct battery measurement up to 6V and on-chip temperature sensing.

Feature Summary

12-bit resolution with 125 kHz sampling rate
Integrated 2.5V internal voltage reference
Supports 4-wire resistive touch screens with on-chip drivers
Includes auxiliary inputs for battery monitoring (0V-6V) and temperature measurement

Applications

Personal Digital Assistants (PDAs)
Portable instruments
Point-of-sale terminals
Cellular phones
Touch screen monitors

Procurement Notes

Verify the specific package designation VFBGA-48 and the industrial temperature range (-40°C to +85°C) against the design requirements. Confirm that the 4x4 mm footprint matches the PCB layout constraints. Check current availability status as distribution channels may vary for this specific package variant.

Selection Notes

Select this component when a compact surface-mount solution is required for resistive touch interfaces. Ensure the system power supply remains within the 2.2V to 5.25V operating range. Verify that the host microcontroller supports the required SPI or QSPI serial interface protocols for data communication.

Part Context

This part belongs to the TSC2046 family, which serves as a low-voltage successor to the ADS7846. It maintains 100% pin compatibility with the ADS7846 across various packages, facilitating easy upgrades in existing designs. The IGQCR suffix specifically denotes the VFBGA-48 package option with industrial temperature rating.
