Hello, 

I want to know is there any way i can use BQ77915 IC to send its data to a MCU such that i can detect SOC/SOH/Voltage etc.

Or i need to use any other IC with this IC or can you suggest me any other protector IC with this feature.

    Hi Ankit,
    BQ77915 is a protector IC and works independently of a MCU. Protectors are usually the second level of protection, and the first level of protection comes from a monitor or a gauge. If you want to communicate the cell voltages and currents to a MCU for system level decisions, but don’t need a pre-packaged gauge solution, then a monitor may be the right choice. For a <=5s battery pack, you might look at BQ76920. 

    BTW here are two videos (1 & 2 - slides can be downloaded too) explaining the differences between a protector, a monitor and a gauge.
