ADuM2250 / ADuM2251
GENERAL DESCRIPTION
The ADuM2250 / ADuM2251 1 are hot swappable digital isolators
with nonlatching, bidirectional communication channels that
are compatible with I 2 C interfaces. This eliminates the need for
splitting I 2 C signals into separate transmit and receive signals for
use with standalone optocouplers.
The ADuM2250 provides two bidirectional channels, supporting
a complete isolated I 2 C interface. The ADuM2251 provides one
bidirectional channel and one unidirectional channel for those
applications where a bidirectional clock is not required.
The ADuM2250 / ADuM2251 contain hot swap circuitry to
prevent data glitches when an unpowered card is inserted onto
an active bus.
These isolators are based on i Coupler? chip scale transformer
technology from Analog Devices, Inc. i Coupler is a magnetic
isolation technology with performance, size, power consump-
tion, and functional advantages compared to optocouplers. The
ADuM2250 / ADuM2251 integrate i Coupler channels with semi-
conductor circuitry to enable a complete, isolated I 2 C interface
in a small form factor package.
