3.3.3 High voltage (HV) power mode examples
Figure 5: USB-Powered HV mode example
Figure 6: LiPo Powered HV example w/ USB charger
Important: The LiPo circuit above is meant to be a generic example of how the BMD-380’s power
modes can be used. Great care must be taken when integrating Lithium-Ion batteries into a
design. Protection circuits suitable for the type of battery used and the application must always
be implemented.
3.4 General purpose I/O
The general purpose I/O is organized as two ports enabling access and control of 44 available GPIO
pins. The first port allows access of P0.00 to P0.31, similar to the one port available on the
BMD-350. The second port allows access to P1.00 to P1.15 (excluding P1.01, P1.04, P1.05, P1.07).
Each GPIO can be accessed individually with the following user configurable features:
Input/output direction
Output drive strength
