^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) [From datasheets] The MAX16065/MAX16066 flash-configurable system managers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) accurately monitor (+/-2.5%) one current channel using a dedicated high-side
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) current-sense amplifier. The MAX16065 manages up to twelve system voltages
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) simultaneously, and the MAX16066 manages up to eight supply voltages.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) The MAX16067 flash-configurable system manager monitors and sequences multiple
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60) system voltages. The MAX16067 manages up to six system voltages simultaneously.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 62) The MAX16068 flash-configurable system manager monitors and manages up to six
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 63) system voltages simultaneously.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 64)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 65) The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 66) system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 67) one current channel using a dedicated high-side current-sense amplifier. The
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 68) MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 69) monitors up to eight supply voltages.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 70)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 71) Each monitored channel has its own low and high critical limits. MAX16065,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 72) MAX16066, MAX16070, and MAX16071 support an additional limit which is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 73) configurable as either low or high secondary limit. MAX16065, MAX16066,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 74) MAX16070, and MAX16071 also support supply current monitoring.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 80) This driver does not probe for devices, since there is no register which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 81) can be safely used to identify the chip. You will have to instantiate
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 82) the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 83) details.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 85) WARNING: Do not access chip registers using the i2cdump command, and do not use
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 86) any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 87) supported by this driver interpret any access to a command register (including
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 88) read commands) as request to execute the command in question. This may result in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 89) power loss, board resets, and/or Flash corruption. Worst case, your board may
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 90) turn into a brick.
