TSC2007IPWRG4

Overview

The TSC2007IPWRG4 is a 12-bit, nano-power resistive touch screen controller manufactured by Texas Instruments. It integrates a high-resolution analog-to-digital converter and a temperature sensor within a single package. The device operates on a supply voltage range of 1.65 V to 3.6 V and features an I2C serial interface for communication with host processors. Designed for low-power applications, it supports 4-wire touch screen interfaces and includes programmable conversion rates. The component is housed in a 16-pin TSSOP package and is rated for operation across an industrial temperature range.

Feature Summary

• 12-bit resolution ADC with integrated temperature sensor
• I2C compatible serial interface supporting standard and fast modes
• Ultra-low power consumption with shutdown mode current less than 0.1 µA
• Programmable touch panel driver output current and ADC conversion rate

Applications

• Handheld mobile devices and smartphones
• Personal digital assistants (PDAs)
• Portable medical instruments
• Industrial control panels with resistive touch screens

Procurement Notes

Verify the suffix 'G4' indicates lead-free and RoHS compliance per Texas Instruments standards. Confirm the 'I' prefix denotes the industrial temperature range (-40°C to +85°C). Ensure the TSSOP-16 package matches the target PCB footprint. Cross-reference the datasheet revision date to ensure compatibility with specific I2C timing requirements.

Selection Notes

Select this component when a 12-bit resolution is sufficient for touch positioning and ultra-low standby power is critical. Compare against the TSC2004 or TSC2005 if SPI interface or higher sampling rates are required instead of I2C. Verify that the system's I2C bus voltage levels are compatible with the 1.65 V to 3.6 V operating range of the controller.

Part Context

The TSC2007 belongs to the TSC200x family of nano-power touch screen controllers from Texas Instruments. This series is designed to replace discrete ADC and touch controller solutions in portable electronics. The IPWRG4 variant specifically denotes the industrial grade version in a TSSOP package with green molding compound and lead-free termination.

Replacement Considerations

The TSC2007IYZGR is a pin-compatible alternative in a DSBGA-12 package. The TSC2004I provides similar functionality but uses an SPI interface instead of I2C. Verify interface compatibility and package dimensions before substituting.
