Summit smb350 battery charger
|
||
|
|
|
||
|
|
The smb350 charger supports stack-cell battery charging.
|
||
|
|
|
||
|
|
The smb350 interface is via I2C bus.
|
||
|
|
The i2c slave 7-bit address is programmable at manufacture.
|
||
|
|
|
||
|
|
Node required properties:
|
||
|
|
- compatible: Must be "summit,smb350-charger".
|
||
|
|
- reg: The device 7-bit I2C address.
|
||
|
|
- summit,stat-gpio gpio which smb350 STAT pin connects to.
|
||
|
|
- summit,chg-en-n-gpio gpio which control charging enable.
|
||
|
|
- summit,chg-susp-n-gpio gpio which control device shutdown
|
||
|
|
- summit,chg-current-ma charging current in milliamps.
|
||
|
|
- summit,term-current-ma charging termination current in milliamps.
|
||
|
|
valid values are 200/300/400/500/600/700.
|
||
|
|
A value of zero means no termination current.
|
||
|
|
|
||
|

||
|
