Figure 6. SMBus Protocols
SMBus Interface (SDA, SCL)
The MAX8709B supports an Intel SMBus-compatible 2-
wire digital interface. SDA is the bidirectional data line
and SCL is the clock line of the 2-wire interface corre-
sponding respectively to SMBDATA and SMBCLK lines of
the SMBus. SDA and SCL are Schmidt-triggered inputs
that can accommodate slow edges; however, the rising
and falling edges should still be faster than 1μs and
300ns, respectively. The MAX8709B use the write-byte,
read-byte, and receive-byte protocols (Figure 6). The
SMBus protocols are documented in System Manage-
ment Bus Specification V1.1 and are available at
http://www.SMBus.org/.
The MAX8709B is a slave-only device and responds to
the 7-bit address 0b01011000 (i.e., with the R/ W bit clear
indicating a write, this corresponds to 0x58). The
MAX8709B has three functional registers: a 5-bit bright-
ness register (BRIGHT4–BRIGHT0), a 3-bit shutdown-
mode register (SHMD2–SHMDE0), and a 2-bit status
register (STATUS1–STATUS0). In addition, the device has
three identification (ID) registers: an 8-bit chip ID register,
an 8-bit chip revision register, and an 8-bit manufacturer
ID register.
