Battery Monitor - Texas Instruments CC253x User Manual

The battery monitor (in the CC2533 only) enables simple voltage monitoring in the devices that do not
include an ADC. It is designed such that it is accurate in the voltage areas around 2 V, with lower
resolution at higher voltages. The registers BATTMON and MONMUX are used to access and control the
functionality of the battery monitor.
The battery monitor can also be used to do simple temperature monitoring by connecting it to the chip
internal temperature sensor instead of the supply voltage. The input is controlled using the MONMUX
register.
