Overview
The TSC2046IPWR is a four-wire resistive touch screen controller manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It features a 12-bit resolution and supports serial interfaces including SPI and SSI with sampling rates up to 125 kS/s. The device operates on a supply voltage range of 2.2 V to 5.25 V, drawing approximately 280 µA during operation. An internal 2.5 V reference source is integrated for auxiliary functions such as battery monitoring and temperature measurement. It maintains pin compatibility with the ADS7846.
Feature Summary
- 12-bit resolution with 125 kS/s sampling rate
- Integrated 2.5 V internal reference voltage
- SPI/SSI serial interface compatibility
- Direct battery measurement and on-chip temperature sensing
Applications
- Wireless communication devices
- Portable consumer electronics
- Medical instrumentation
- HVAC control panels
Procurement Notes
Verify the specific suffix 'G4' if RoHS compliance details require confirmation beyond standard manufacturer declarations. Confirm the TSSOP-16 package dimensions (5mm x 4.4mm) against PCB layout requirements. Ensure the design accounts for the 2.2 V minimum operating voltage for low-power applications.
Selection Notes
Select this component when a direct replacement for the ADS7846 is required without redesigning the footprint. Choose the TSC2046IPWR over the IRGVR variant if surface-mount technology using TSSOP packaging is preferred over VQFN. Verify that the host microcontroller supports the required SPI or SSI protocol for data retrieval.
Part Context
This part belongs to the TSC2046 series of touch screen controllers from Texas Instruments. It serves as a modernized successor to legacy controllers like the ADS7846, offering improved power efficiency while maintaining electrical compatibility. The IPWR designation specifically identifies the TSSOP-16 package variant within this family.
Replacement Considerations
The TSC2046IPWRG4 is a verified equivalent variant within the same product line, differing primarily in manufacturing lot specifications rather than functional parameters.
