TSC2046IRGVR

The TSC2046IRGVR is a 4-wire resistive touchscreen controller from Texas Instruments. It features a 12-bit ADC, supports 1.5V to 5.25V operation, and includes an on-chip temperature sensor. Key functions include touch pressure measurement, touch position detection (X/Y coordinates), and low-power modes.
It communicates via SPI and integrates a 2.5V reference voltage, reducing external components. The device is designed for portable electronics like PDAs, smartphones, and industrial control panels.
Packaged in a VQFN-16 (RGV) form factor, it offers compact, space-efficient integration. Its low-power consumption (typ. 0.7mW at 3.6V) makes it ideal for battery-powered applications.
Key features:
- 12-bit resolution
- On-chip temp sensor
- SPI interface
- Low-power modes
- Pen interrupt output
Applications include touchscreens, medical devices, and handheld instruments.
