Texas Instruments Current Regulation/Management INA271AQDRZF

The INA271AQDRZF is a current-shunt monitor from Quarktwin Technology Ltd. designed for automotive applications. It operates within a common-mode voltage range of -16 V to +80 V and can sense voltage drops across current shunts, independent of the supply voltage. This device features a voltage output and is available with a gain option of 20 V/V, making it suitable for various applications including electric power steering, body control modules, and brake systems. The INA271AQDRZF operates from a single supply voltage of 2.7 V to 18 V, with a maximum supply current of 900 OºA. It has a bandwidth of up to 130 kHz, which facilitates its use in current-control loops. The device is AEC-Q100 qualified, ensuring reliability in automotive environments, and is specified over an extended temperature range of -40¬8C to +125¬8C. It comes in an SOIC-8 package, optimized for external filtering, and offers high accuracy with a common-mode rejection ratio (CMRR) of 120 dB and minimal offset drift.
