The 1.5 mA supply current is modest enough to keep the thermal budget in check on a densely populated automotive ECU.

For a single-channel replacement, the INA254A1IPWAR offers a zero-drift architecture with 350 kHz bandwidth and 2.4 V/µs slew rate, though its supply range and package differ. Neither is a direct pin-for-pin substitute — verify the footprint and supply rails before swapping."},{"question":"Can INA293B3QDBVRQ1 be used for high-side current sensing?","answer":"Yes. As a current sense amplifier, it is designed to measure the voltage across a shunt resistor placed between the supply rail and the load (high-side) or between the load and ground (low-side). The wide supply range of 2.7 V to 20 V accommodates common automotive battery rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA293B3QDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA293B3QDBVRQ1 when reusing this data.
