title: Flash LED device inside Qualcomm Technologies, Inc. PMICs

description: |
Flash LED controller is present inside some Qualcomm Technologies, Inc. PMICs.
The flash LED module can have different number of LED channels supported
e.g. 3 or 4. There are some different registers between them but they can
both support maximum current up to 1.5 A per channel and they can also support
ganging 2 channels together to supply maximum current up to 2 A. The current
will be split symmetrically on each channel and they will be enabled and
disabled at the same time.
