Power Control Jumper:

1) To power from Debug install jumper on pins 5 - 6

2) To power from Target USB install jumper on pins 3 - 4

3) To power from BoosterPack 5V install jumper on pins 1 - 2

This is also the off position if BoosterPack does not

supply power

When powered from BoosterPack TPS2052B does not

provide current limit protection.

When powered by BoosterPack, USB host mode does not

supply power to connected devices

Primary 3.3V regulator

Disconnect JP3 to power device from 3V3 BoosterPack

JP2 can be used to measure MCU current

consumption with a multi-meter.

TPS2052B provides current limit for main 5V power.

Also provides power switching for USB host/OTG modes

For Host/OTG:

PD6 configured as USB0EPEN peripheral function.

PQ4 configure as individual pin interrupt. Indicates

power fault on the USB bus. USB0PFLT peipheral pin

not available due to pin mux and use on BoosterPacks.

USB Host mode does not supply power to devices

when powered from a BoosterPack

For Applications that do not use USB:

Configure PD6 as input with internal pull-down

enabled. Turns off power to TARGET_VBUS

R38 and C3 Used to meet

VBAT rise time requirements

R41 may be removed and precision
