Key Features
- 9-channel integrated power management consolidates multiple buck converters and LDOs into a single 56-pin VQFN IC, reducing BOM complexity in automotive SoC power trees
- 2.8 V to 5.5 V wide input voltage range supports direct powering from automotive 3.3 V or 5 V regulated rails in ADAS and infotainment ECUs
- AEC-Q100 automotive-qualified (RQ1 suffix) with extended temperature and reliability testing for safety-critical vehicle applications
- Integrated power sequencing and supervisory functions eliminate external sequencing logic and reduce system-level design effort for multi-rail processors
Applications
TPS65941213RWERQ1 is designed to power multi-rail automotive SoCs and application processors in ADAS cameras, radar ECUs, and connected infotainment head units where a single PMIC must supply 9 independent voltage domains from a 5 V system bus. Its AEC-Q100 automotive qualification ensures reliable operation across the -40°C to 125°C temperature range demanded by underhood and cockpit electronic modules. The 56-pin VQFN package and integrated power sequencing reduce board area and external component count compared to discrete multi-regulator solutions in space-constrained automotive ECU designs.

Frequently Asked Questions
How many power output channels does TPS65941213RWERQ1 integrate and what types of regulators are included?
TPS65941213RWERQ1 integrates 9 power channels in a single PMIC, combining multiple buck (step-down) converters and LDO regulators to supply the full power tree of an automotive SoC or multi-core processor. This eliminates 6–9 discrete regulator ICs and their associated passive components from the bill of materials, saving significant PCB area and assembly cost in ADAS ECUs.
What input voltage range does TPS65941213RWERQ1 accept in automotive system designs?
TPS65941213RWERQ1 operates from 2.8 V to 5.5 V input, with a 6 V absolute maximum rating, making it compatible with the 3.3 V and 5 V regulated bus voltages common in automotive ECU power architectures. The wide range allows it to operate through 5 V supply sag events during cold-crank or load-dump transients without dropping out of regulation.
Is TPS65941213RWERQ1 qualified for safety-critical automotive modules such as ADAS radar or forward cameras?
Yes, TPS65941213RWERQ1 carries the RQ1 automotive qualification suffix, indicating AEC-Q100 Grade 1 qualification with operating junction temperature from -40°C to 125°C. This qualification level meets the reliability requirements of ADAS radar, surround-view camera, and advanced driver information systems, providing the MTBF and failure-rate data required for ISO 26262 safety analysis.
What package does TPS65941213RWERQ1 use and how does it affect PCB thermal management in an automotive ECU?
TPS65941213RWERQ1 is housed in a 56-pin VQFN package with an exposed thermal pad, providing a compact footprint of approximately 8 mm x 8 mm. The exposed pad solders directly to a PCB thermal via array, achieving a junction-to-board thermal resistance of around 10°C/W to 20°C/W, enabling the PMIC to supply all 9 channels in automotive temperature environments without external heatsinks.
