TSC2003IPWRG4

Overview

The TSC2003IPWRG4 is a resistive touch screen controller manufactured by Texas Instruments. It features an integrated 12-bit analog-to-digital converter (ADC) and operates on a single power supply ranging from 2.7 V to 5.5 V. The device supports I2C and SPI serial interfaces, enabling efficient data transfer with minimal pin count. Designed for low-power applications, it includes a built-in temperature sensor and programmable internal reference. The component is housed in a 16-pin TSSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated 12-bit ADC with up to 200 kSPS sampling rate
• Dual interface support: I2C and SPI
• Built-in temperature sensor for environmental monitoring
• Low power consumption with shutdown mode capability

Applications

• Handheld mobile devices requiring resistive touch input
• Industrial control panels with HMI interfaces
• Portable medical equipment with user input requirements

Procurement Notes

Verify the suffix G4 indicates lead-free and RoHS compliance per Texas Instruments standards. Confirm the IPWR designation corresponds to the TSSOP-16 surface-mount package. Ensure the operating voltage range aligns with the system's 2.7 V to 5.5 V supply rails. Check for availability of the specific revision level if long-term supply is required.

Selection Notes

Select this model when both I2C and SPI compatibility are needed for flexibility in host processor integration. The integrated temperature sensor eliminates the need for external thermal components in space-constrained designs. Ensure the host system can handle the serial protocol timing requirements for reliable communication at the specified sampling rates.

Part Context

This component belongs to the TSC2003 series of touch screen controllers from Texas Instruments. It is part of a family designed for cost-effective and low-power resistive touch solutions. The G4 suffix typically denotes a green/RoHS-compliant version of the standard TSC2003IPWR part.

Replacement Considerations

Direct replacements include other members of the TSC200x series such as TSC2003IPWR or TSC2003IDR, provided the package type matches the PCB footprint. Cross-model substitution with ADS7843 requires interface adaptation due to different communication protocols.
