Power management integrated circuits (PMICs) are a class of integrated circuits that provide power supply sequencing, resetting and monitoring, and often house simple system power supplies. Supervisors are one type of PMIC, and the MAX6310UK25D1-T is an example of a supervisor IC for battery-powered systems and portable electronic devices. This IC provides protection and reset control for systems using multiple supply voltages and a single battery.

Features

The MAX6310UK25D1-T is a 6-pin supervisor IC that features integrated low-dropout (LDO) regulators, supervised system reset control, and a wide range of user-selectable operating thresholds. The operating thresholds can include (but are not limited to) battery voltage monitoring, system voltage monitoring, manual reset, and low battery voltage reset. The reset delay for this IC can also be programmed by the user. Other features include programmable brown-out reset (BOR) drive strength, battery monitoring reset delay, enable and open-drain reset output options, and extended battery life.

Applications

The MAX6310UK25D1-T supervisor IC is ideal for a wide range of applications including digital still cameras, personal digital assistants (PDAs), portable navigation and GPS systems, automotive systems, and portable power products. It can also be used in battery-powered systems that are powered by multiple supply rails. This IC can also be used in communication systems and low-voltage, low-power systems.

Working Principle

The MAX6310UK25D1-T supervisor IC works by monitoring the voltage on its input pins and outputting a logic-level reset signal when certain conditions are met. The monitored voltages can include the system voltage, the battery voltage, or one of the integrated LDO regulators. When the monitored voltage falls below a predetermined threshold, the reset output will be activated, resetting the system. The reset delay can also be programmed, allowing for longer delays in resetting the system. The reset signal from this IC will be a logic level, controlled by the enable and open-drain reset outputs. The output signals can then be used to reset the system.

In addition, the MAX6310UK25D1-T supervisor IC also has integrated low-dropout (LDO) regulators. These regulators can be used to provide power to devices that need a regulated voltage source, such as sensors and motor controllers. The voltage output of the LDO can be adjusted by the user, allowing for a range of voltage outputs. The MAX6310UK25D1-T also features a brown-out reset (BOR) drive strength that can be programmed by the user. This allows the device to protect its systems from damage in case of a power surge or brownout.

Conclusion

The MAX6310UK25D1-T supervisor IC is a versatile, user programmable device that can be used in a wide range of applications. Its features include integrated low-dropout (LDO) regulators, supervised system reset control, a wide range of user-selectable operating thresholds, programmable brown-out reset (BOR) drive strength, battery monitoring reset delay, and enable and open-drain reset output options. This IC is ideal for digital still cameras, PDAs, portable navigation and GPS systems, automotive systems, portable power products, communication systems, and low-voltage, low-power systems.
