High-side or Low-side Measurement Bi-Directional Current and Power Monitor with I2C Compatible Interface

SGM837.pdf

The SGM837 is a 16-bit ultra-precision I²C and SMBus compatible interface current, voltage, power monitor with alert function. It operates in a wide common-mode voltage range from 0V to 36V and a single 2.7V to 5.5V power supply.

The device has three operating modes: continuous, triggered and power-down modes that can reduce quiescent current. Programmable averaging and conversion times allow for more flexibly to fit the timing requirements in a variety of applications. It also integrates alert functions with configured priority.

Considering the low input bias current feature, the device is capable of applying a larger sensing resistor, so as to ensure the accuracy of current detection within micro-amp range.

The SGM837 is available in a Green MSOP-10 and TDFN-3×3-10L package. It is specified over the operating temperature range of -40℃ to +125℃.
