Overview
The TSC2046EIPWRG4 is a low-voltage, four-wire resistive touch screen controller manufactured by Texas Instruments. It features a 12-bit analog-to-digital converter (ADC) with a sampling rate of 125 kS/s. The device operates on a supply voltage range of 2.2 V to 5.25 V and supports low-voltage digital I/O interfaces, including SPI and SSI. It integrates an internal 2.5 V reference voltage source for auxiliary inputs, battery monitoring, and temperature measurement. The component is housed in a 16-pin TSSOP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution ADC with 125 kS/s sampling rate
- Internal 2.5 V reference voltage source
- 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 'G4' suffix indicates lead-free packaging compliant with RoHS standards. Confirm the industrial temperature grade (-40°C to +85°C) matches system requirements. Check current lifecycle status as some sources indicate obsolescence notices for related variants. Ensure the TSSOP-16 footprint aligns with PCB design constraints.
Selection Notes
Select this model for applications requiring direct replacement for ADS7846 due to pin compatibility. Choose the TSC2046 series over higher-speed alternatives if power consumption is critical, noting the typical operating current. Verify that the 12-bit resolution meets the precision needs of the specific touch panel application.
Part Context
This component belongs to the TSC2046 family of touch screen controllers from Texas Instruments. It serves as a successor or alternative to the ADS7846, offering similar functionality with enhanced low-voltage capabilities. The part is categorized under Data Converter ICs and Touch Screen Controllers.
Replacement Considerations
The TSC2046IPWR is a pin-compatible active alternative. The TSC2046EIPW is a tube-packaged variant of the same core device. Verify electrical specifications against ADS7846 datasheets for legacy board upgrades.
