Abracon ABX80X I2C ultra low power RTC/Alarm chip
|
|
|
|
The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
|
|
ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
|
|
is the superset of ab180x.
|
|
|
|
Required properties:
|
|
|
|
- "compatible": should one of:
|
|
"abracon,abx80x"
|
|
"abracon,ab0801"
|
|
"abracon,ab0803"
|
|
"abracon,ab0804"
|
|
"abracon,ab0805"
|
|
"abracon,ab1801"
|
|
"abracon,ab1803"
|
|
"abracon,ab1804"
|
|
"abracon,ab1805"
|
|
Using "abracon,abx80x" will enable chip autodetection.
|
|
- "reg": I2C bus address of the device
|
|
|
|
Optional properties:
|
|
|
|
The abx804 and abx805 have a trickle charger that is able to charge the
|
|
connected battery or supercap. Both the following properties have to be defined
|
|
and valid to enable charging:
|
|
|
|
- "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
|
|
- "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
|
|
resistor, the other values are in ohm.
