Power Supply
UC-08-M37 EN R1.0
voltage and current of V_BCKP.
In the case of normal power supply to the evaluation board, the micro battery
charging circuit on the
board
will automatically charge the micro battery.
If the
board
has been placed for a long time, the power of the battery may be low
and the hot start test may fail. Therefore, it
is recommended to charge the
board
as
long as possible before testing the hot start function.
(1)
Use a multimeter to measure the voltage of the micro battery. If the voltage is
above 2.6 V and is stable, it indicates that the power of the micro battery is
sufficient.
(2)
Use a multimeter to measure the voltage of the micro battery. If the voltage
drops rapidly, it indicates that the power of the micro battery is insufficient.
(3)
When the micro battery runs out of power, it will take more than 96 hours to fully
charge the battery.
(4)
Under normal circumstances, after powering the board for one night, the hot
start test can be done normally
the next day.
