B.3 Power to Peripheral Boards
DCIN and Vcc are available on friction-lock connector terminals J5 and J7 to power
peripheral boards that may be used with the BL2600.
Figure B-2. Pinout Friction-Lock Connector Terminals J5 and J7
Keep in mind that the BL2600 draws 377 mA from the Vcc supply, and that the diode at D41
(shown in Figure B-1) can handle at most 1 A at V
RAW
, so that leaves the remaining current
capacity to be shared among the DCIN and Vcc pins on friction-lock connector terminals
J5 and J7. Table B-1 lists the available current at DCIN based on the current drawn at Vcc.
