SGM842
3-Channel, High-Side or Low-Side Measurement, Shunt and Bus Voltage Monitor with I2C- and SMBus-Compatible Interface
The SGM842 is a high accuracy, three-channel, power monitor with an I2C- and SMBus-compatible interface which can sense high-side or low-side current and bus voltage. It supports a wide common-mode voltage range from 0V to 30V. For more flexibly, the ADC conversion times and sample averaging modes are allowed to be programmed according to the requirements. Additionally, both critical and warning alerts are reported for each channel.
The SGM842 operates over an input voltage range of 2.7V to 5.5V and draws 1000µA (TYP) of supply current. It supports four programmable addresses.
The SGM842 is available in a Green TQFN-4×4-16L package and specified over a junction temperature range of -40℃ to +125℃.
