FEATURES
Hot Swappable, Dual I
2
C Isolators, 5 kV
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
iCoupler®
chip scale transformer
technology from Analog Devices, Inc.
iCoupler
is a magnetic
isolation technology with performance, size, power consump-
tion, and functional advantages compared to optocouplers. The
ADuM2250/ADuM2251
integrate
iCoupler
channels with semi-
conductor circuitry to enable a complete, isolated I
2
C interface
in a small form factor package.
Bidirectional I
2
C communication
Open-drain interfaces
Suitable for hot swap applications
30 mA current sink capability
1000 kHz operation
3.0 V to 5.5 V supply/logic levels
16-lead SOIC wide body package version (RW-16)
16-lead SOIC wide body enhanced creepage version (RI-16-2)
High temperature operation: 105°C
Safety and regulatory approvals
UL recognition: 5000 V rms for 1 minute per UL 1577
CSA Component Acceptance Notice 5A (RI-16-2 package)
IEC 60601-1: 250 V rms (reinforced)
IEC 60950-1: 400 V rms (reinforced)
VDE certificate of conformity
