4.4 Under Voltage Protection
When the voltage of the SYS_PWR pin drops below
the voltage level of 2.9V, the system will shutdown
automatically.
4.5 Ambient Detection
The BM62/64 module has a built-in ADC for charger
thermal protection. Figure 4-3 illustrates the suggested
circuit and thermistor, Murata NCP15WF104F. The
charger thermal protection can avoid battery charge in
restricted temperature range. The upper and lower
limits for temperature values can be configured by
using the UI tool.

Note: Thermistor must be placed close to the
battery in the user application for accurate
temperature measurements and to enable
thermal shutdown feature.
