Addressing the Device
(except for some devices that have extended, 10−bit
addresses). When the master device sends a device address
over the bus, the slave device with that address responds.
The ADM1032 and the ADM1032−1 are available with one
SMBus address, which is Hex 4C (1001 100). The
ADM1032−2 is also available with one SMBus address;
however, that address is Hex 4D (1001 101).

x = don’t care bits, and y = SMBus timeout bit.
Default = 0. See SMBus section for more information.
Writing to Address 0F causes the ADM1032 to perform a single measurement. It is not a data register as such and it does not
matter what data is written to it.

Serial Bus Interface
The ADM1032 is connected to this bus as a slave device,
under the control of a master device.
enabled, the SMBus times out after typically 25 ms of no
activity. However, this feature is not enabled by default. To
enable it, set Bit 7 of the consecutive alert register
(Address = 22h).
Control of the ADM1032 is carried out via the serial bus.
There is a programmable SMBus timeout. When this is
The serial bus protocol operates as follows:
1. The master initiates data transfer by establishing a
START condition, defined as a high−to−low
transition on the serial data line SDATA, while the
serial clock line SCLK remains high. This
indicates that an address/data stream follows. All
slave peripherals connected to the serial bus
respond to the START condition and shift in the
next eight bits, consisting of a 7−bit address (MSB
first) plus an R/W bit, which determines the
