DESCRIPTION
The TSC2003 is a 4-wire resistive touch screen controller. It
also features direct measurement of two batteries, two aux-
iliary analog inputs, temperature measurement, and touch-
pressure measurement.
The TSC2003 has an on-chip 2.5V reference that can be
utilized for the auxiliary inputs, battery monitors, and tem-
perature-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.
