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 touchpressure measurement.
The TSC2003 has an on-chip 2.5V 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 will operate down to 2.7V supply voltage while monitoring the battery voltage from 0.5V to 6V.
The TSC2003 is available in the small TSSOP-16 and VFBGA-48 packages and is specified over the –40°C to +85°C temperature range.
