It integrates five regulated outputs from a single 4.5 V to 36 V input, covering the full automotive battery range including cold-crank and load-dump transients.
The wide input range means this PMIC sits directly on the 12 V battery bus without a pre-regulator.
For a safety-critical automotive program that runs five to seven years, this means the PMIC stays in the BOM without a forced redesign.
The base product number TPS65381 covers a family of pin-compatible variants. The TPS65381AQDAPR (without the Q1 suffix) shares the same footprint and output configuration but may lack the full AEC-Q100 qualification. Confirm the specific variant grade against your program's qualification requirements before substituting.
