Binding for TI bq25890 Li-Ion Charger
|
|
|
|
Required properties:
|
|
- compatible: Should contain one of the following:
|
|
* "ti,bq25890"
|
|
- reg: integer, i2c address of the device.
|
|
- ti,battery-regulation-voltage: integer, maximum charging voltage (in uV);
|
|
- ti,charge-current: integer, maximum charging current (in uA);
|
|
- ti,termination-current: integer, charge will be terminated when current in
|
|
constant-voltage phase drops below this value (in uA);
|
|
- ti,precharge-current: integer, maximum charge current during precharge
|
|
phase (in uA);
|
|
- ti,minimum-sys-voltage: integer, when battery is charging and it is below
|
|
minimum system voltage, the system will be regulated above
|
|
minimum-sys-voltage setting (in uV);
|
|
- ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV);
|
|
- ti,boost-max-current: integer, maximum allowed current draw in boost mode
|
|
(in uA).
|
|
|
|
Optional properties:
|
|
- ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz,
|
|
otherwise 1.5MHz;
|
|
- ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the
|
|
input current will be the lower between the resistor setting and the IINLIM
|
|
register setting;
|
|
- ti,thermal-regulation-threshold: integer, temperature above which the charge
|
|
current is lowered, to avoid overheating (in degrees Celsius). If omitted,
|
|
the default setting will be used (120 degrees);
|
|
|
|
Example:
|
|
|
|
bq25890 {
|
|
compatible = "ti,bq25890";
|
|
reg = <0x6a>;

|
ti,battery-regulation-voltage = <4200000>;
|
|
ti,charge-current = <1000000>;
|
|
ti,termination-current = <50000>;
|
|
ti,precharge-current = <128000>;
|
|
ti,minimum-sys-voltage = <3600000>;
|
|
ti,boost-voltage = <5000000>;
|
|
ti,boost-max-current = <1000000>;
|
|
|
|
ti,use-ilim-pin;
|
|
ti,thermal-regulation-threshold = <120>;
|
|
};
