The MAX6855UK42D1+T is mainly used for power management and supervision in portable applications. It is suitable for use in a wide variety of embedded and mobile applications, such as industrial and medical equipment, smartphones, tablet PCs, etc. It can support up to eight power domains and monitor up to eight Supervisory pins.

Working Principle

The MAX6855UK42D1+T is an integrated power management and supervisory IC. It can be used to provide power delivery and monitoring needs of various devices and systems. The MAX6855UK42D1+T is a low power device with extremely high integration level, low cost and high performance. The MAX6855UK42D1+T integrates a complete set of power domains and monitoring circuits. It includes a voltage regulator, a single-switch Buck Converter, a load switch, and a battery charger. The power domains can be configured to different operational modes such as Low-Power, Low-Voltage, High-Voltage, Battery-Charger, or Hi-Power mode. The power domains can be autonomously controlled by configurating with separate logic levels.The IC also features a power monitor and safety monitor functions. The power monitor can monitor voltage, current and temperature of the Power Domains and take corrective actions accordingly, while the safety monitor detects and reports any abnormality in supply, load or configuration. The integrated Supervisory pins can be used to monitor the voltage, current and/or temperature of each pin. The Supervisory pins are configurable to trigger an interrupt if the monitored value exceeds its limit. This feature helps to ensure safe supply of power to the system, by detecting any fault or abnormality in the power source or load.

Conclusion

The MAX6855UK42D1+T is a highly integrated single-chip power management IC with supervisors. It is suitable for use in a wide range of portable and embedded applications. It can provide power delivery and monitoring needs of various devices and systems, including up to eight power domains, integrated voltage regulator, single-switch Buck Converter, load switch, and battery charger. It also features a power monitor and safety monitor functions, and configurable Supervisory pins to monitor voltage, current and/or temperature. The MAX6855UK42D1+T thus provides excellent power management, supervision, and safety features in a compact form factor, making it suitable for a wide range of applications.
