MAX6650/MAX6651
Fan-Speed Regulators and Monitors
with SMBus/I2C-Compatible Interface
6
_______________________________________________________________________________________
The MAX6650/MAX6651 employ three standard SMBus
protocols: write byte, read byte, and receive byte
(Figure 2). The shorter protocol (receive) allows quicker
transfers, provided that the correct data register was
previously selected by a write or read byte instruction.
Use caution with the shorter protocol in multimaster
systems, since a second master could overwrite the
command byte without informing the first master.
Slave Addresses
The device address can be set to one of four different
values. Accomplish this by pin-strapping ADD so that
more than one MAX6650/MAX6651 can reside on the
same bus without address conflicts (Table 1).
