The power supply circuit of the ACD52832 consists of two main parts: A step-up 
regulator which provides co5V for on-board devices, independent of the actual 
battery voltage.




In a second stage, +3.3V are supplied through a LDO from the 

reg5V rail.




Note:




The +3.3V_DBG connection supplies the Segger J-Link 

programming and debugging device. This device is first powered up when the charging 
controller confirms a stable power supply.
