Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADUM1252AUA device is an ultra-low power, bidirectional I2C isolator with extended VDD, idle bus hot swap, and low VOL capabilities. The ADuM1252 has a 1.71V to 5.5V independent power supply on both the first and second sides of the isolator. The device operates at frequencies up to 2MHz. Each side provides an ultra-low standby current of 21μA, ideal for battery powered systems.

Features:

Low VOL(MAX) enables higher I2C suite compatibility

First side: 0.69V

Second side: 0.4V

Ultra-low power consumption extends battery life

142μA per channel at 400 kHz (typical)

The wide independent VDD1/VDD2 power supply range supports more logical voltage levels and level switching

Both sides are 1.71V to 5.5V

Enhanced hot-swap second-side I/O

The initial 2-side connection occurs when the bus is idle or stopped to prevent data corruption

Two-way I2C data transmission up to 2MHz SCL

Bidirectional SCL for advanced bus topologies

Supports clock extension across isolation grids and multiple controllers

The strong current filling capability reduces the RPULL-UP value for faster bus speeds

First side: 5mA

Second side: 50mA

Robust electrical isolation for digital signals

Sustainable Tolerance (VIOWM)

8-pin narrow-body SOIC: 445VRMS

Can withstand ±10kV surge, in line with IEC 61000-4-5 standards

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.

• 2.Are all our products genuine?
