Power supply system
The kit has the following input voltage sources:
5 V from KitProg3 USB Micro-B port (J4)
•
LiPo battery @ 3.7 V, 350 mAh (J3)
•
USB connector
Figure 30
The LiPo battery is connected to the LiPo battery charger IC (U10) with a 10µF bypass capacitor. The LiPo battery
charger takes the VBUS (5V) from the USB connector (J4) as a source for charging the battery as well as the supply
(VOUT) for other components when battery power is not available. A yellow LED (LED5) attached to the
of the charger IC indicates the battery charging status by glowing continuously. It automatically turns off when
the battery is fully charged. The TS pin is meant for an external negative temperature coefficient (NTC)
