17 additional information and example.
21 const: maxim,max77693-charger
23 maxim,constant-microvolt:
25 Battery constant voltage in uV. The charger will operate in fast
26 charge constant current mode till battery voltage reaches this level.
27 Then the charger will switch to fast charge constant voltage mode.
28 Also vsys (system voltage) will be set to this value when DC power is
29 supplied but charger is not enabled.
30 Valid values: 3650000 - 4400000, step by 25000 (rounded down)
35 maxim,min-system-microvolt:
37 Minimal system voltage in uV.
38 enum: [3000000, 3100000, 3200000, 3300000, 3400000, 3500000,
42 maxim,thermal-regulation-celsius:
44 Temperature in Celsius for entering high temperature charging mode.
45 If die temperature exceeds this value the charging current will be
46 reduced by 105 mA/Celsius.
47 enum: [70, 85, 100, 115]
50 maxim,battery-overcurrent-microamp:
52 Overcurrent protection threshold in uA (current from battery to
54 Valid values: 2000000 - 3500000, step by 250000 (rounded down)
59 maxim,charge-input-threshold-microvolt:
61 Threshold voltage in uV for triggering input voltage regulation loop.
62 If input voltage decreases below this value, the input current will
63 be reduced to reach the threshold voltage.
64 enum: [4300000, 4700000, 4800000, 4900000]
