    Hello James,

    The HW-101A is a  raw Hall element, and TI only has Hall ICs.  From the function of the HW-101A, I believe a linear magnetic sensor would best suite your needs.

    For Hall effect sensors, we have the DRV5053, DRV5055, DRV5056, and DRV5057.  Of these, the DRV5056 is the closest to the same function, but does not have the same type of sensitivity. 

    Because of the high sensitivity of the HW-101A, I would recommend looking into the DRV425.  This is a highly sensitive linear magnetic sensor (fluxgate technology) with adjustable gain and range.
