description: |
This is a part of device tree bindings for Maxim MAX77693 MicroUSB Integrated
Circuit (MUIC).
See also Documentation/devicetree/bindings/mfd/maxim,max77693.yaml for
additional information and example.
properties:
compatible:
const: maxim,max77693-charger
maxim,constant-microvolt:
description: |
Battery constant voltage in uV. The charger will operate in fast
charge constant current mode till battery voltage reaches this level.
Then the charger will switch to fast charge constant voltage mode.
Also vsys (system voltage) will be set to this value when DC power is
supplied but charger is not enabled.
Valid values: 3650000 - 4400000, step by 25000 (rounded down)
minimum: 3650000
maximum: 4400000
default: 4200000
maxim,min-system-microvolt:
description: |
Minimal system voltage in uV.
enum: [3000000, 3100000, 3200000, 3300000, 3400000, 3500000,
3600000, 3700000]
default: 3600000
maxim,thermal-regulation-celsius:
description: |
Temperature in Celsius for entering high temperature charging mode.
If die temperature exceeds this value the charging current will be
reduced by 105 mA/Celsius.
enum: [70, 85, 100, 115]
default: 100
maxim,battery-overcurrent-microamp:
description: |
Overcurrent protection threshold in uA (current from battery to
system).
Valid values: 2000000 - 3500000, step by 250000 (rounded down)
minimum: 2000000
maximum: 3500000
default: 3500000
maxim,charge-input-threshold-microvolt:
description: |
Threshold voltage in uV for triggering input voltage regulation loop.
If input voltage decreases below this value, the input current will
be reduced to reach the threshold voltage.
enum: [4300000, 4700000, 4800000, 4900000]
default: 4300000
