+description: |
+ The BQ2515x family is a highly integrated battery charge management IC that
+ integrates the most common functions for wearable devices, namely a charger,
+ an output voltage rail, ADC for battery and system monitoring, and
+ push-button controller.
+
+ Specifications about the charger can be found at:
+ http://www.ti.com/lit/ds/symlink/bq25150.pdf
