The Texas Instruments TPS65311QRVJRQ1 is an automotive-grade power management IC from the TPS65311 family, AEC-Q100 qualified for under-hood and chassis-domain applications. It operates from a 4V to 50V supply rail — wide enough to ride through cold-crank dips and load-dump transients on a 12V or 24V automotive bus — and draws just 44 µA quiescent current, which keeps the always-on module within the standby budget.
Yes.
No official pin-compatible second source or cross-reference is listed for this exact order code. The base product number TPS65311 covers multiple variants; confirm the specific suffix for your BOM position.
The supply current is 44 µA. For always-on automotive modules (body controllers, telematics, keyless entry), this quiescent current keeps the total dark-current draw within the vehicle's sleep-mode budget, avoiding battery drain over extended parking periods.
