Using 4x INA303 together with DRV8313 (basically the TI reference design) for current sensing a BLDC.

    Hello Dav01,

    Thanks for considering to use Texas Instruments.  We have two other current shunt monitors with comparators that are in smaller packages.  However, they do have some key differences from the INA303.  One device is the INA301, which only has an alert but no analog output pin.  The other device is the INA381, which has a lower bandwidth.  Both devices only have one comparator and the delay for their ALERTs are not tunable.
