Figure 63. Additional Temperature Measurement for Differential Temperature Reading
OPERATION - BATTERY MEASUREMENT
An added feature of the TSC2300 is the ability to monitor the battery voltage which may be much larger than the
supply voltage of the TSC2300. An example of this is shown in Figure 64, where a battery voltage ranging up to 6V
may be regulated by a dc/dc converter or low-dropout regulator to provide a lower supply voltage to the TSC2300. The
battery voltage can vary from 0.5 V to 6 V while maintaining the voltage to the TSC2300 at a level of 2.7 V-3.6 V. The
input voltage on VBAT1 is divided down by 4 so that a 6.0V battery voltage is represented as 1.5 V to the A/D, while the
input voltage on VBAT2 is divided by 2 so that 3.0-V battery voltage is represented as 1.5 V to the A/D. If the battery
voltage is low enough, the 1.2 V internal reference can be used to decrease LSB size, potentially improving accuracy.
The battery voltage on VBAT1 must be below 4* VREF, and the voltage on VBAT2 must be below 2* VREF. Due to
constraints of the internal switches, the input to the A/D after the voltage divider cannot be above 1.5 V or VREF,
whichever is lower. In order to minimize the power consumption, the divider is only ON during the sampling of the
battery input.
