BD9576MUF and BD9573MUF are power management ICs primarily intended for
|
|
powering the R-Car series processors.
|
|
The IC provides 6 power outputs with configurable sequencing and safety
|
|
monitoring. A watchdog logic with slow ping/windowed modes is also included.

description:

|
BD9576 and BD9573 VOUT1 regulator enable state can be individually
|
|
controlled by a GPIO. This is dictated by state of vout1-en pin during
|
|
the PMIC startup. If vout1-en is LOW during PMIC startup then the VOUT1
|
|
enable sate is controlled via this pin. Set this property if vout1-en
|
|
is wired to be down at PMIC start-up.

description:

|
Watchog timeout in milliseconds. If single value is given it is
|
|
the maximum timeout. Eg. if pinging watchdog is not done within this time
|
|
limit the watchdog will be triggered. If two values are given watchdog
|
|
is configured in "window mode". Then first value is limit for short-ping
|
|
Eg. if watchdog is pinged sooner than that the watchdog will trigger.
|
|
When two values is given the second value is the maximum timeout.
|
|
# (HW) minimum for short timeout is 2ms, maximum 220 ms.
|
|
# (HW) minimum for max timeout is 4ms, maximum 4416 ms.
