    The target voltage regulator is a MIC5353 variable output LDO. The on-board debugger can adjust the voltage output supplied to the board target section by manipulating the MIC5353’s feedback voltage. The hardware implementation User Guide DS50003143A-page 13 © 2021 Microchip Technology Inc.
  • Page 14 This will detect and handle any short-circuit conditions. It will also detect and handle if an external voltage, which causes VCC_TARGET to move outside of the voltage setting monitoring window of ±100 mV, is suddenly applied to the VTG pin without setting the VOFF pin low. User Guide DS50003143A-page 14 © 2021 Microchip Technology Inc.
  • Page 15 The VBUS output pin has a PTC fuse to protect the USB against short circuits. A side effect of the PTC fuse is a voltage drop on the VBUS output with higher current loads. The chart below shows the voltage versus the current load of the VBUS output. User Guide DS50003143A-page 15 © 2021 Microchip Technology Inc.
