Temperature
The TSC2101 supports programmable auto-temperature measurement mode, which can be enabled using
control register 0CH/page 1. In this mode, the TSC2101 can auto-start the temperature measurement after a
programmable interval. The user can program minimum and maximum threshold values through a register. If
the measurement goes outside the threshold range, the TSC2101 sets a flag in the read only control register
0CH/page 1, which gets cleared after the flag is read. The TSC2101 can also be configured to send and active
high interrupt over GPIO1 by setting D9 in control register 0CH/page 1. The duration of the interrupt is
approximately 2 ms.
Temperature measurement can only be done in host controlled mode.
Battery Measurement
An added feature of the TSC2101 is the ability to monitor the battery voltage on the other side of a voltage
regulator (dc/dc converter), as shown in Figure 33. The battery voltage can vary from 0.5 V to 6 V while
maintaining the analog supply voltage to the TSC2101 at 3.0 V to 3.6 V. The input voltage (VBAT) is divided
down by a factor of 5 so that a 6.0 V battery voltage is represented as 1.2 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/D output code of B, the voltage at the battery pin can be calculated as:
VBAT +

VREF
Where:
N is the programmed resolution of A/D
VREF is the programmed value of internal reference or the applied external reference.
