The TSC2003 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 TSC2003 has an on-chip 2.5-V reference that can be utilized for the auxiliary inputs, battery monitors, and temperature-measurement modes. The reference can also be powered down when not used to conserve power. The internal reference operates down to 2.7-V supply voltage while monitoring the battery voltage from 0.5 V to 6 V. The TSC2003 is available in the small TSSOP-16 package and is specified over the –40°C to 85°C temperature range.
