MAX706ASEPA+

Power Management Integrated Circuits (PMICs) are components that are used to provide integrated and reliable circuits for the electric power management of electronic products. For system-level power management chips, Supervisors, the most important sub-class of PMICs, are based on specific designs and components to ensure correct and safe use of electric power. MAX706ASEPA+ is one of the many PMICs supervisors that features of higher current limit and much better performance compared to traditional power management solutions. This article will focus on the different applications of MAX706ASEPA+ and its working principle.

Application Field of MAX706ASEPA+

The MAX706ASEPA+ supervisor provides a complete power management solution comprised of a low-voltage detect (LVD) circuit, three-state reset output, a low-power standby circuitry, and internal reset template that works to enable systems to achieve power requirements set forth in the ATX, SFX, and WTX standards. Therefore, it is suitable for a wide range of power related applications, including desktop, server, and home office products that use ATX, SFX, or WTX power supply standards. Furthermore, it also makes it ideal for applications that require a highly reliable voltage supervisory system like guidance systems for jet engines and engines for electric cars, automobile tire pressure monitoring system and other automotive electronics.

Working Principle of MAX706ASEPA+

The MAX706ASEPA+ is an ultra low power voltage supervisor used to monitor the input voltage ranges from 0.9V to 9.0V. It has an internal supply voltage of 2.25V while the reset voltage can be set through a selection of divider resistor values. It is also equipped with a power-on reset generator that is capable of providing longer reset delay time (tRST) and shorter Power-Loss Threshold time (tPLO).

When the supply voltage rises to the level set by the regulation resistor, a reset signal commands the processor to reset its internal state. During a reset period, the reset output is activated and held low until the voltage reaches the set threshold, and then is deactivated. Meanwhile, when the input voltage drops below the preset threshold, a reset signal will be produced to reset the processor. The processor will stay in the reset status until the voltage rises back to the regulation voltage level, and then the processor will come out of the reset status.

In addition, MAX706ASEPA+ also features of higher current limit of 20mA, with a voltage range of 4.4V to 24V for better performance and reliability. Furthermore, it has a low current consumption of 0.90uA at 2.25V, making it highly suitable for portable electronic products that require low power consumption.

Conclusion

In conclusion, MAX706ASEPA+ is a type of Supervisors of PMIC that provides high current limit, a wide voltage range and high reliability. Its applications are wide and varied, and suitable for a wide range of devices and systems, including desktop and server products that use ATX, SFX, or WTX power supply standards, as well as automotive, military and aeronautical applications. Its working principle is simple and very effective, and involves resetting a processor when the input voltage drops below a preset threshold level and vice versa. With its many advantages, MAX706ASEPA+ is an ideal choice for many markets.
