Register Address: 02
Default Value=0000 1010 (0AH)
R/W
Charger output “float” voltage; programmable from 3.5 to 4.44V in 20mV
increments; defaults to 000010 (3.54V), see Table 3
R/W OTG pin active LOW
OTG pin active HIGH
R/W Disables OTG pin
Enables OTG pin
Register Address: 03 or 3B
Default Value=100X X100
R Identifies Fairchild Semiconductor as the IC supplier
R Part number bits, see the Ordering Info on page 1
R IC Revision, revision 1.X, where X is the decimal of these three bits
Register Address: 04
Default Value=1000 1001 (89H)
W
Writing a 1 resets charge parameters, except the Safety register (Reg6), to their
defaults: writing a 0 has no effect; read returns 1
R/W Programs the maximum charge current, see Table 5
R Unused
R/W Sets the current used for charging termination, see Table 6
