1*4882a593SmuzhiyunAbracon ABX80X I2C ultra low power RTC/Alarm chip 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunThe Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801, 4*4882a593Smuzhiyunab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805 5*4882a593Smuzhiyunis the superset of ab180x. 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunRequired properties: 8*4882a593Smuzhiyun 9*4882a593Smuzhiyun - "compatible": should one of: 10*4882a593Smuzhiyun "abracon,abx80x" 11*4882a593Smuzhiyun "abracon,ab0801" 12*4882a593Smuzhiyun "abracon,ab0803" 13*4882a593Smuzhiyun "abracon,ab0804" 14*4882a593Smuzhiyun "abracon,ab0805" 15*4882a593Smuzhiyun "abracon,ab1801" 16*4882a593Smuzhiyun "abracon,ab1803" 17*4882a593Smuzhiyun "abracon,ab1804" 18*4882a593Smuzhiyun "abracon,ab1805" 19*4882a593Smuzhiyun "microcrystal,rv1805" 20*4882a593Smuzhiyun Using "abracon,abx80x" will enable chip autodetection. 21*4882a593Smuzhiyun - "reg": I2C bus address of the device 22*4882a593Smuzhiyun 23*4882a593SmuzhiyunOptional properties: 24*4882a593Smuzhiyun 25*4882a593SmuzhiyunThe abx804 and abx805 have a trickle charger that is able to charge the 26*4882a593Smuzhiyunconnected battery or supercap. Both the following properties have to be defined 27*4882a593Smuzhiyunand valid to enable charging: 28*4882a593Smuzhiyun 29*4882a593Smuzhiyun - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V) 30*4882a593Smuzhiyun - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output 31*4882a593Smuzhiyun resistor, the other values are in kOhm. 32
