SMBUS INTERFACE
All communications over the SMBus are interpreted by the
SMBus interface block. The SMBus interface is a SMBus
slave device. All internal LTC4110 registers may be updated
and accessed through the SMBus interface as required.
The SMBus protocol is a derivative of the I 2 C-Bus TM . (For
a complete description of the bus protocol requirements,
reference “The I 2 C-Bus and How to Use It, V1.0” by Phil-
ips ? , and “System Management Bus Speci?cation, Version
1.1,” from the SMBus organization). See Table 6: Register
Command Set Description and Table 7: Summary of Sup-
ported SMBus Functions, for complete details.
All data is clocked into the shift register on the rising edge
of SCL. All data is clocked out of the shift register on the
falling edge of SCL. Detection of an SMBus Stop condi-
tion, or power-on reset will reset the SMBus interface to
an initial state at any time. The LTC4110 command set is
interpreted by the SMBus interface and passed onto the
charger controller block as control signals or updates to
internal registers. Smart battery charge commands are
