ADUM152N1BRZ-RL7

The ADUM152N1BRZ-RL7 is available in fail-safe high or low options and is housed in a compact 16-lead, RoHS-compliant SOIC package. The components are versatile and find use in a variety of applications including industrial automation, automotive electronics, consumer electronics, and energy management. It ensures efficient power usage, seamless voltage compatibility, and reliability in high temperature environments, all in a compact design.

·General-purpose multichannel isolation

·Serial peripheral interface (SPI)/data converter isolation

·Industrial field bus isolation

The ADuM150N/ADuM151N/ADuM152N1 are 5-channel digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 4.5 ns at 5 V operation. Channel to channel matching of propagation delay is tight at 4.0 ns maximum.

The ADuM150N/ADuM151N/ADuM152N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available by which the outputs transition to a predetermined state when the input power supply is not applied.
