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 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.
