The LTC
1623 SMBus switch controller is a slave device
that controls two high-side N-channel MOSFETs on either
the SMBus or the I
2
C bus. The LTC1623 operates with an
input voltage from 2.7V to 5.5V with a low standby current
of 14
μ
A (at 3.3V). In accordance with the SMBus specifi-
cation, the LTC1623 maintains the 0.6V V
IL
and 1.4V V
IH
input thresholds throughout the supply voltage range.
Using the 2-wire interface, CLK and DATA, the LTC1623
monitors the bus for a start condition (DATA going from
high to low while CLK is high). Once detected, the LTC1623
compares its address with the first (address) byte sent
over the bus from the master. If matched, the LTC1623 will
execute the second (command) byte from the master and
independently control the built-in charge pumps to drive
two external switches.
The LTC1623 has two three-state programmable address
pins, thus allowing eight different addresses and a total of
sixteen available switches on the same bus.
