The SQ52201E which has an I2C or SMBUS-compatible interface, is a high accuracy device with the features of current shunt, bus voltage and power monitor. 

The shunt voltage and the bus supply voltage could be sampled accurately at the same time and will be processed inside the device to generate the power data with programmable calibration, averaging technique and internal multiplier. It makes the application system more reliable because of abundant alert sources settings provided by programmable alert function. 

The current on common mode bus voltages can be monitored by SQ52201E. The common mode bus voltages can vary from 0V to 36V, which is independent of the supply voltage, ranging from 2.7V to 5.5V. The operating temperature of SQ52201E ranges between –40°C and +125°C. The SQ52201E is available in the MSOP-10 package and features 16 programmable addresses on the I2C-compatible interface.
