SMH4804 Datasheet, PDF (8/41 Pages) Summit Microelectronics, Inc. – -48V Programmable Hot Swap Sequencing Power Controller

Functional Description
Serial Interface
The SMT4804 uses the industry standard I²C, 2-wire serial
data interface. This interface provides access to the
configuration registers and the nonvolatile fault latch. The
interface has three address inputs (A0 - A2) allowing up to
eight devices on the same bus. This allows multiple devices
on the same board or multiple boards in a system to be
controlled with two signals; SDA and SCL.
Device configuration utilizing the Windows based SMT4804
graphical user interface (GUI) is highly recommended. The
software is available from the Summit website
(www.summitmicro.com). Using the GUI in conjunction with
this datasheet, simplifies the process of device prototyping
and the interaction of the various functional blocks. A
programming Dongle (SMX3200) is available from Summit
to communicate with the SMT4804. The Dongle connects
directly to the parallel port of a PC and programs the device
through a cable using the I²C bus protocol.
