The 100 µV input offset voltage keeps measurement error low even with small shunt voltages.
The 20 V maximum supply span means the part can sit directly on a nominal 12 V battery line (which can spike to 18 V during cold crank) without a pre-regulator. The 1.5 mA supply current is moderate — fine for a powered module, but not the lowest draw for a battery-backed always-on sense node.
Yes, the INA281A5QDBVRQ1 is part of the Automotive, AEC-Q100 series. It is qualified for automotive-grade applications, including under-hood and chassis-domain electronics.
The INA281A5QDBVRQ1 is offered in a SC-74A, SOT-753 package, with the supplier device package specified as SOT-23-5. It is a surface-mount package suited for automated assembly.
