Power management integrated circuits (PMIC) are integrated circuit devices that manage the power flow and thermal design of an electronic system, including the components that deliver electrical current. The MAX17073ETJ+, specially designed for power management, is an integrated PMIC that features high efficiency, low power loss, robust short-circuit protection and thermal overload protection.

Application Field

The MAX17073ETJ+ is designed for use in portable applications, such as cellular phones, PDAs, digital cameras and handheld computers. It is specifically designed to provide a simple and efficient solution for charging and discharging Li-Ion/Li-polymer batteries. This PMIC utilizes a low-noise charge pump, low quiescent current buck converters, a selectable 3-state charger, and a buck-boost converter for floating battery topologies.

The MAX17073ETJ+ also features programmable Linear and Pulse Charging, allowing users to set their own charge profiles. This feature eliminates the need for external regulated voltage sources and maintains a safe system space. Additionally, power-on time and temperature monitoring are included to enhance system protection.

Working Principle

The MAX17073ETJ+ is a micro-power control IC used to regulate DC outputs and protect Li-Ion/Li-polymer battery cells. The PMIC consists of a low noise charge pump, low quiescent current buck converters, a selectable 3-state charger, and a buck-boost converter for floating battery topologies.

The PMIC works by first connecting the battery power and load output to the PMIC\'s input and output connectors respectively. The charge pump then recirculates the power from the system load back to the battery. The buck converters then regulate the output voltage and current of the battery. Finally, the selectable 3-state charger and buck-boost converter maintain the battery\'s power level.

The PMIC also contains onboard current source and voltage divider that samples the output voltage and current, allowing the PMIC to monitor the battery and system performance during the charge and discharge cycles. This data is then analyzed to determine the remaining capacity of the battery and the remaining available power to the load.

In addition, the MAX17073ETJ+ provides various built-in protection features, such as Over-Charge, Over-Discharge, Over-Current and Short-Circuit, to protect the system from any overuse or misuse of the battery in terms of both charge and discharge. The PMIC includes programmable Linear and Pulse Charging, allowing users to set their own charge profiles, and Power-On time and temperature monitoring for system protection.

Conclusion

The MAX17073ETJ+ is an advanced power management integrated circuit specifically designed for portable applications. It features low quiescent current buck converters, a selectable 3-state charger, and a buck-boost converter for floating battery topologies. The onboard current source and voltage divider sample output voltage and current, allowing the PMIC to monitor the system\'s performance during charge and discharge cycles. Additionally, various protection features are provided to protect the system from any overuse or misuse of the battery.
