 ### Power Tree
 ![Power tree](assets/maxCarrierPowerTree.svg)
 
-The Portenta Max Carrier can either be powered through the power jack (X1) or a 18650 Li-ion/LiPo battery (J16, J18). The MPM3550EGLE (U6) provides a +5V rail to power the peripherals. This IC also provides power to the BQ24195RGET IC (U11) that manages the Li-ion battery and boosts the voltage to +5V. U11 also determines the battery status. Priority is with the jack delivered power. The battery charger IC also outputs a +3V8 power rail that powers the modem (U1). The +5V power rail provides power to the Portenta board that regulates the voltage with its onboard buck converter to +3V3. The +3V3 power rail supplies power to the LoRa module (U23), 4-port USB hub (U3), microSD module (J11) and Fieldbus circuitry (U4). Audio is powered by a dedicated AP7311 LDO regulator that provides a low noise +1V8 power rail.

 The debugger circuitry has a dedicated power supply AP2112K (U14) that runs off the micro USB voltage from J10. This enables the debugger to operate even if the Portenta board is not inserted.
