| Binding for TI bq25890 Li-Ion Charger |
| |
| This driver will support the bq25892, the bq25896 and the bq25890. There are |
| other ICs in the same family but those have not been tested. |
| |
| Required properties: |
| - compatible: Should contain one of the following: |
| * "ti,bq25890" |
| * "ti,bq25892" |
| * "ti,bq25895" |
| * "ti,bq25896" |
| - 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>; |
| }; |
