Product Summary

The TSC2003IZQCR is a 4-wire resistive touch screen controller. It also features direct measurement of two batteries, two auxiliary analog inputs, temperature measurement, and touch-pressure measurement. The TSC2003IZQCR has an on-chip 2.5V reference that can be utilized for the auxiliary inputs, battery monitors, and temperature-measurement modes. The applications of the TSC2003IZQCR are personal digital assistants, portable instruments, point-of-sales terminals, pagers, touch screen monitors, cellular phones. The internal reference will operate down to 2.7V supply voltage while monitoring the battery voltage from 0.5V to 6V.
