TSC2000IPWRG4

Overview

The TSC2000IPWRG4 is a resistive touch screen controller manufactured by Texas Instruments. It integrates a 12-bit Analog-to-Digital Converter (ADC) with a sampling rate of up to 125 kSPS and a built-in temperature sensor. The device operates on a single power supply ranging from 1.8 V to 5.5 V, consuming low quiescent current. It supports serial communication via SPI or 3-wire interfaces and includes an internal reference voltage. The component is housed in a 16-pin TSSOP package and is designed for applications requiring precise coordinate detection and system monitoring.

Feature Summary

• Integrated 12-bit ADC with 125 kSPS sampling rate
• Built-in temperature sensor for system monitoring
• Internal 2.5 V reference voltage source
• Low power consumption with shutdown mode

Applications

• Resistive touch screen controllers
• Portable electronic devices
• Industrial control panels

Procurement Notes

Verify the specific suffix IPWRG4 corresponds to the TSSOP-16 package and RoHS compliance status. Confirm the operating temperature range matches the -40°C to +85°C industrial specification. Ensure the supplier provides documentation confirming the absence of lead-based materials as indicated by the G4 designation.

Selection Notes

Select this component when a resistive touch interface requires integrated ADC functionality without external conversion hardware. The internal reference simplifies board design compared to parts requiring external references. Consider the 12-bit resolution and 125 kSPS speed for required response times. Verify power supply constraints align with the 1.8 V to 5.5 V input range.

Part Context

The TSC2000 belongs to the TSC2000 series of touch screen controllers from Texas Instruments. This family shares common architectural features such as the 12-bit ADC and serial interface capabilities. Variants within the series may differ in package options or specific feature sets like additional wiper outputs, but the core conversion and control logic remain consistent across the group.

Replacement Considerations

Direct substitutes include other models from the TSC2000 series such as the TSC2003 or TSC2004, provided pin compatibility and feature requirements are met. Cross-referencing datasheets is necessary to confirm interface compatibility and electrical specifications before substitution.
