Qualcomm Technologies, Inc. BCL OFF cooling device
|
|
|
|
The BCL OFF cooling device, will be used to disable PMIC bcl.
|
|
This cooling device will be called when modem RF calibration
|
|
is performed using external power supply.
|
|
|
|
When external power supply is used for RF calibration, ibat current
|
|
can cross the battery specs and can trigger batfet issues. So pmic bcl
|
|
should be disabled as it is for protection for battery not external
|
|
power supply.
