standard 2-wire I 2 C host device. In addition, the device
6.10 I C/SMBus Device Address Selection
is compatible with SMBus version 2.0 and includes an
SALRT line to help mitigate bandwidth limitations
related to continuous fault monitoring. Pull-up resistors
are required on the I 2 C/SMBus. The ZL2004 accepts
most standard PMBus commands. When controlling
the device with PMBus commands, it is recommended
that the enable pin is tied to SGND.

When communicating with multiple SMBus devices
using the I 2 C/SMBus interface, each device must have
its own unique address so the host can distinguish
between the devices. The device address can be set
Address values are right-justified.

If additional device addresses are required, a resistor
to provide up to 25 unique device addresses. In this
case, the SA1 pin should be tied to SGND.
If more than 25 unique device addresses are required or
if other SMBus address values are desired, both the SA0
and SA1 pins can be configured with a resistor to SGND
SMBus address = 25 x (SA1 index) + (SA0 index)
