Power Management - Specialized

The MAX9504BEUT+ is a highly integrated power management integrated circuit (PMIC) specifically designed to provide fast system power-up, power-down and power management for next-generation portable products. The MAX9504BEUT+ integrates numerous features and technologies to provide a cutting-edge power management solution in one IC. With this highly integrated solution, designers are enabled to reduce component count, improve system performance and reduce time to market.

Overview of MAX9504BEUT+ Features

This PMIC integrates several functions into one IC, delivering a complete power management solution for any system. It includes a 5V DCDC Buck Converter, two low dropout linear regulators, one adjustable linear regulator, two ultra-low quiescent current LDO regulators, programmable clocking and reset support, a power FET gate driver, two low power sleep and shutdown modes, a general-purpose switch mode controller, and system-level fault monitoring and protection.

The 5V DCDC Buck Converter can deliver up to 1A of output and supports an input voltage range of 2.5V to 5.5V. It also has an embedded synchronous rectifier and an integrated internal power FET to reduce external component requirements, improving system efficiency.

The integrated ultra-low quiescent current LDO regulators provide output accuracy of ±1.5%, with a minimum quiescent current of only 0.6μA. The adjustable linear regulator provides excellent load and line regulation with variable output range from 0.6V to 5V.

The MAX9504BEUT+ also includes programmable clocking and reset support, with the ability to select from an integrated 32kHz, 16kHz or 8kHz clock or an external clock, as well as selectable watchdog timeout periods of 1.25s, 2.5s, 5s, 10s, 20s or disabled.

A flexible power-up sequence generator also provides a wide range of options for generating the power-up sequence for up to four supplies in both single-stage and cascaded configuration. This simplifies the design of complex power system, eliminating the need for additional controllers to manage these complex power-up and power-down sequences.

The MAX9504BEUT+ also features a dual power FET driver, designed to drive both NFET and PfET switches. It supports adjustable maximum duty cycles, as well as adjustable slew rates, allowing the system designer to optimize the power efficiency.

For system protection, the MAX9504BEUT+ provides fault monitoring and system protection functions. This includes an input overvoltage protection, switch overvoltage protection, an over-temperature shutdown circuit, and reverse protection for the charger input voltage.

Lastly, the MAX9504BEUT+ includes two low power sleep and shutdown modes, including a shutdown mode and a deep sleep mode. The shutdown mode powers down all uncommitted cores, while the deep sleep mode powers down all uncommitted cores and the Buck Converter.

Benefits of MAX9504BEUT+

The MAX9504BEUT+ offers several benefits that make it an ideal solution for powering next-generation portable products. Its highly integrated feature set enables designers to reduce component count and complexity, resulting in reduced time to market and lower cost.

The PMIC also features a wide operating temperature range, enabling robust system performance in a variety of environments. It also offers best-in-class system accuracy, providing improved load regulation and stressing load regulation stability under load transient conditions.

The integrated low power sleep and shutdown modes enable low power operation in all operating conditions, making it ideal for battery powered applications. The input and switch overvoltage protection provide additional system protection in the event of system faults or power surges.

Conclusion

The MAX9504BEUT+ is a high-integrity power management IC that delivers a complete power management solution for next-generation portable products. Its numerous features and technologies help designers to reduce system complexity and improve system efficiency, while its wide range of system protections keep the system safe from harm. In short, it offers an ideal solution for any system power management application.
