TSC2046 Description

Short technical summary and product information.

The TSC2046 from Texas Instruments is a 4-wire touch screen controller that offers a low-voltage I/O interface, supporting operation from 1.5V to 5.25V. It is 100% pin-compatible with the ADS7846, allowing for easy upgrades.

 

Key features include an internal 2.5V reference that can be powered down to conserve energy. The device supports direct battery measurement from 0V to 6V, on-chip temperature measurement, and touch-pressure measurement. It interfaces via QSPI and SPI 3-wire protocols and includes auto power-down functionality.

 

With a low power consumption of less than 0.75mW typical at 2.7V (reference off) and a high sample rate of up to 125kHz, the TSC2046 is well-suited for battery-operated portable equipment. It is specified for operation between -40°C and +85°C.

 

The TSC2046 is available in TSSOP-16, QFN-16, and VFBGA-48 packages, making it adaptable to various design requirements.
