7.4.1 System Management Bus (SMBus) Mode

If MODE_SEL = L, the LMH0324 is in SMBus mode. In SMBus mode, Pins 10 and 21 are configured as SDA and SCL. Pins 7 and 20 act as 4-level address straps for ADDR0 and ADDR1 at power up to determine the 7-bit slave address of the LMH0324, as shown in Table 6.

Table 6. SMBus Device Slave Addresses(1)

ADDR0
(LEVEL) 		ADDR1
(LEVEL) 		7-BIT SLAVE
ADDRESS [HEX] 		8-BIT WRITE
COMMAND [HEX]
L L 1D 3A
L R 1E 3C
L F 1F 3E
L H 20 40
R L 21 42
R R 22 44
R F 23 46
R H 24 48
F L 25 4A
F R 26 4C
F F 27 4E
F H 28 50
H L 29 52
H R 2A 54
H F 2B 56
H H 2C 58
(1) The 8-bit write command consists of the 7-bit slave address (Bits 7:1) with 0 appended to the LSB to indicate an SMBus write. For example, if the 7-bit slave address is 0x1D (001 1101'b), the 8-bit write command is 0x3A (0011 1010'b).
