One. Overview of TI INA201AQDGKRQ1:

The TI INA201AQDGKRQ1 is a low-side or high-side shunt monitor with a voltage output. The INA201AQDGKRQ1 device is capable of sensing the voltage drop across the shunt at common-mode voltages ranging from -16V to +80V. Three output voltage levels are available, 20V/V, 50V/V and 100V/V, with bandwidths up to 500kHz.

The INA201AQDGKRQ1 also integrates an open-drain comparator and an internal voltage reference with a voltage threshold of 0.6V. An external voltage divider sets the current trip point. The comparator is latched and can be brought into a transparent state by grounding (or floating) the RESET pin.

The INA201AQDGKRQ1 operates from a single 2.7V to 18V supply with a maximum supply current of 1800μA. These devices are available in an ultra-small VSSOP-8 package and are specified over an extended ambient temperature range of -40°C to +125°C.
