3 . Description
GXI330 is a high and low side voltage, current, and power consumption monitoring chip. The 16 bit ADC integrated inside the chip continuously measures the bus voltage VBUS and the voltage division value VSHUNT of the high/low side resistance RSHUNT on the bus, and calculates the current flowing through the bus and the power consumption generated on the bus based on this. The bus voltage range that GXI330 can measure is 0-30V. GXI330 can directly output current measurement results in amperes (A) and power measurement results in watts (W), greatly reducing the subsequent data processing of the host.  
The power supply voltage range of GXI330 is 2.7~5.5V, and the typical current power consumption during normal operation is 300 μ A. The typical operating temperature range of GXI330 is -40~+125 ° C. GXI330 is compatible with standard I2C interfaces for communication as low as 1.6V and has 16 programmable slave addresses. GXI330 offers two packaging options: 12-BALL WLCSP (GXI330W) and 10 PIN MSOP (GXI330U).  
The GXI330 can be configured to measure only the bus voltage VBUS or the high and low side resistance voltage division VSHUNT, with a minimum conversion time of only 140 μ s.
GXI330 can provide average output to achieve more accurate measurement results.
GXI330 has ALERT pin and programmable alarm threshold, which can provide real-time protection for other devices on the bus in various usage scenarios.
