The LP873244RHDTQ1 is a four-rail power management IC from Texas Instruments, combining two 2A step-down buck converters and two 300mA LDOs. It is qualified to AEC-Q100, operates from 2.8V to 5.5V input, and switches at 2MHz.
The package with wettable flank terminals supports automated optical inspection of solder joints.
No direct pin-compatible replacement has been announced. The LP873244RHDTQ1 is the current active device for this function; no second-source alternate is listed.
Yes, the input voltage range is 2.8V to 5.5V, so it works directly on a 5V automotive rail and can tolerate cold-crank dips down to 2.8V.
Yes, it is listed under the Automotive, AEC-Q100 series, meeting the stress and reliability qualification for automotive applications.
