Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADUM1255AWA is an I2C isolator with idle bus hot swap and low VOL, which provides two open-drain channels, one unidirectional and one bidirectional, for applications that require bidirectional data transfer over the same line but have a unidirectional clock, such as I2C. To prevent latching behavior, the first side output contains a special buffer that adjusts the logic low-level voltage to 0.64V, and the input logic low-level threshold is at least 50mV lower than the output logic low-level voltage. The second side has a traditional buffer that does not adjust the logic low-level output voltage.

The ADuM1255 has an independent power supply from 2.25V to 5.5V on both the first and second sides of the isolator. The suite operates at frequencies up to 2MHz.

The ADuM1255 first precharges the bus pins, then monitors the bus status to find an idle bus or detect an I2C stop condition, and then connects side 1 and side 2 to provide a distract-free bus connection for a hot-swappable connection on side 2.

The ADuM1255 comes in an 8-pin narrow-body SOIC package. The suite is rated for operating ambient temperatures ranging from -40°C to +125°C.

Applications:

Isolated I2C/SMBus interface

Battery management system

Power over Ethernet (PoE)

Motor control system

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.
