Power management integrated circuits, or PMICs, offer a compact solution to combine multiple power source, power distribution and power management functions into a single chip. Specialized PMICs provide design engineers with the necessary flexibility to achieve their objectives in a variety of power systems. ST’s STLUX385ATR is a specialized PMIC which can be used in a variety of applications, thanks to its advanced characteristics. This article will explain the applications and working principles of the STLUX385ATR.

Versatility of the STLUX385ATR

The STLUX385ATR is capable of providing up to four separate outputs, ranging from 0.9V to 5.5V. Each output is digitally programmable, with a single output accuracy of 0.4%. This enables engineers to design multiple power supply rails in a single package, simplifying design and speeding up time-to-market. A key feature of the STLUX385ATR is that each output rail can be dynamically adjusted to manage the power draw of the system’s loads. This enables the STLUX385ATR to be used in a variety of applications, such as consumer electronics, embedded systems, and automotive applications. The STLUX385ATR also provides advanced protection functions to protect the system from short circuit, thermal over-load, and undervoltage, ensuring the reliability of the system.

Unique Power Management Capabilities

The STLUX385ATR also offers unique power management capabilities that make it an ideal choice for a wide range of applications. For instance, the STLUX385ATR supports dynamic power gating for its outputs. This allows the system to be adapted on-the-fly, providing the flexibility to deliver the correct power to the correct load at the correct time. This reduces the overall system power consumption, especially during idle and sleep mode.Furthermore, the STLUX385ATR also supports sequencing functions, allowing multiple supply rails to be sequenced without the need for external components. This simplifies the design and can reduce the total BOM cost for the system. Finally, the STLUX385ATR offers built-in cycle-by-cycle peak current-limit protection, ensuring that the system can cope with transient loads without any thermal or short-circuit risks.

Conclusion

The STLUX385ATR is a specialized PMIC which provides engineers with flexibility in a variety of power systems. It is capable of providing up to four separate outputs, ranging from 0.9V to 5.5V, with a single output accuracy of 0.4%. The STLUX385ATR also offers advanced protection functions, dynamic power gating, sequencing, and cycle-by-cycle peak current-limit protection, making it ideal for a wide range of applications. With its advanced characteristics, the STLUX385ATR is a great choice for any power system.
