Temperature measurement can only be done in host controlled mode.
Battery Measurement
An added feature of the TSC2100 is the ability to monitor the battery voltage on the other side of a voltage regulator (dc/dc
converter), as shown in Figure 22. The battery voltage can vary from 0.5 V to 6 V while maintaining the analog supply
voltage to the TSC2100 in the range of 2.7 V to 3.6 V. The input voltage (VBAT1 or VBAT2) is divided down by a factor of
6 so that a 6.0-V battery voltage is represented as 1.0 V to the ADC. In order to minimize the power consumption, the divider
is only on during the sampling of the battery input. If the battery conversion results in a ADC output code of B, the voltage
at the battery pin can be calculated as
Vbat = (B/2^N)*6*Vref
where N is the programmed resolution of ADC and Vref the programmed value of internal reference or the applied external
reference.

Figure 22. Battery Measurement Functional Block Diagram
For increased protection and robustness, TI recommends a minimum 100 resistor be added in series between the system
battery and the VBAT pin. The 100 resistor will cause an approximately 1% gain change in the battery voltage
measurement, which can easily be corrected in software when the battery conversion data is read by the operating system.
