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.
