The SGM843 is a 12-bit high-precision I2C and SMBus compatible interface current, voltage, power monitor with alert function. It operates in a wide common-mode voltage range from -0.3V to 28V and a single 2.7V to 5.5V power supply. 

The SGM843 has three operating modes: continuous, triggered and shutdown modes that can reduce quiescent current. Programmable averaging and conversion times allow for more flexibility to meet the timing requirements in a variety of applications. It monitors the bus voltage existing on the IN- pin continuously. Besides, it also integrates alert functions with configured priority and can be capable of triggering an alert in cases of over-current, under-current, over-voltage, under-voltage or over-power conditions. 

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 SGM843 is available in a Green WLCSP-0.75×1.5-8B package. It is specified over the operating temperature range of -40℃ to +85℃.
