It can be used to power low-power to medium-power embedded systems, allowing engineers to expand their product offerings while saving time in their design cycle. It also offers a wide range of features that allow flexible design implementation and lower system power dissipation.

Features of the ACT8810QJ1B3-T

The ACT8810QJ1B3-T provides system designers with a wide range of features that help simplify system design and improve system performance. These features include a high-accuracy voltage reference, 16-level voltage and current control, 5.0 V power sequencing output, power supply sequencing, power fault detection, power-on reset function, over-temperature protection, voltage and current monitors, low-power reset function, power fail comparator, and low-voltage detection.

Working Principle of the ACT8810QJ1B3-T

The basic process followed by the ACT8810QJ1B3-T to provide power to the system starts with a system power supply. This supply powers the ACT8810QJ1B3-T which then uses voltage regulation, current regulation and power sequencing logic to provide system power. The voltage and current regulations are adjusted via a 16-level control system. The power sequencing function controls the order in which the various supplies come on line and shuts them down in a specific order in the event of a system shutdown. The power control feature ensures that the system power supply stays within its predetermined parameters at all times and the power-on reset circuit helps protect the system from uncontrolled power-on transients.In addition, the ACT8810QJ1B3-T also provides advanced protection against power overload, over temperature, and undervoltage to maximize system reliability. The power fail comparator monitors the system power supply levels to prevent catastrophic failure and the low-voltage detection circuit protects against voltage levels that might unintentionally cause system damage.

Conclusion

The ACT8810QJ1B3-T is an advanced single-chip PMIC from Accuracy Technologies that is designed for use in a variety of consumer, industrial, and automation applications. It combines multiple system power management functions, such as voltage and current generation, power sequencing, power supply sequencing, and power control into a single device for simple system design and enhanced system performance. It also provides protection against power overload, over temperature, and undervoltage to maximize system reliability.
