Overview
The TSC2046IRGVR is a resistive touch screen controller manufactured by Texas Instruments, designed for low-voltage digital I/O applications. It features a 12-bit resolution and supports sampling rates up to 125 kS/s. The device operates on a supply voltage range of 2.2 V to 5.25 V with a typical operating current of 280 uA. Communication is handled via Serial, 3-Wire, SPI, or SSI interfaces. It is housed in a 16-VQFN package suitable for surface mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution with 125 kS/s sampling rate
- Supports Serial, 3-Wire, SPI, and SSI interfaces
- Low power consumption with 280 uA operating current
- Operates on 2.2 V to 5.25 V supply voltage
Applications
- Resistive touch screen control systems
- Portable electronic devices requiring low voltage operation
- Industrial control panels with serial interface requirements
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation as required for regulatory adherence. Check humidity sensitivity levels for proper storage and handling procedures during assembly.
Selection Notes
Select this component for designs requiring a single-channel resistive touch controller with flexible serial communication options. Ensure the system voltage aligns with the 2.2 V to 5.25 V input range. Consider the 16-VQFN package dimensions for PCB layout constraints compared to other variants like the IPWR.
Part Context
This part belongs to the TSC2046 series from Texas Instruments, which includes various packages such as TSSOP-16 (IPWR) and BGA (IGQCR). The IRGVR variant specifically denotes the VQFN-16 package form factor, distinguishing it from leaded or larger footprint alternatives within the same functional family.
Replacement Considerations
TSC2046IRGVT serves as a tape-and-reel alternative within the same package type. For different packaging needs, TSC2046IPWR offers the same functionality in a TSSOP-16 package.
