SGM837
High-side or Low-side Measurement Bi-Directional Current and Power Monitor with I2C Compatible Interface
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 package. It is specified over the operating temperature range of -40℃ to +125℃.
