TPS2HCS10-Q1: SNS function

Part Number: TPS2HCS10-Q1
Other Parts Discussed in Thread: TPS2HB16-Q1

Hi TI,

I want to sense the current of CH1 and CH2 through the SNS pin instead of the internal ADC, could you please help to guide me the required SPI command and sequence? Thanks.

    One more question, if  both ISNS_DIS_CH1 and ISNS_DIS_CH2 are bit 0, which channel is sensed at the SNS pin? Thanks.

    Hello,

    There would not really be a great way to use the SNS pin directly to measure the output current and the device multiplexes the channels and the current sense information is used during the I2T sensing.

    Could you help me understand what the the device is being used for? A device such as the TPS2HB16-Q1 might work better as it will have a direct current mirror implementation that would be output via the SNS pin.

    Best Regards,
    Tim
