DESCRIPTION

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.
