PMIC – Supervisor is commonly used in electronic applications to monitor and control various aspects of the system, like input and output voltages, system current, temperature, and other parameters. The MAX6316LUK29BX/V+T is one such supervisor designed specifically for mobile and portable electronic applications. It incorporates two supervisor feature sets in one device: an interface voltage supervisor, and an input voltage supervisor. This article will look at the application field and working principle of the MAX6316LUK29BX/V+T.

Application Field

The MAX6316LUK29BX/V+T is suitable for a wide range of mobile and portable electronic applications, including smartphones, PDAs, and portable media players. This part features very low current consumption, making it an ideal choice for battery powered applications. It integrates two supervisor features in one single device, which saves board space, time, and money in the design stage of the application.

The MAX6316LUK29BX/V+T includes a low-voltage system reset, along with fault detect delay, power-on reset monitoring, voltage level suspension, and temperature monitoring. It detects input voltage levels in the range of 1.2V to 3.3V, with an accuracy of ±1.5%. It operates at a temperature range of -40°C to +85°C, and is available in a 0.4mm × 0.4mm WLCSP package, making it suitable for use in very small devices.

Working Principle

The MAX6316LUK29BX/V+T works by continuously monitoring the voltage levels and current draw of the system. It uses an internal bandgap reference to accurately measure the input voltage at the supply pin. If the voltage drops below the reset threshold, the supervisor will trigger a reset command to the system. The reset command is sent via a low-power open-drain output, along with status flags to indicate any voltage level or temperature abnormalities.

The MAX6316LUK29BX/V+T also includes an interface feature set, which monitors the consistency of the system voltage and can be used to set up a manual reset command. The MAX6316LUK29BX/V+T also integrates a temperature monitor feature, which allows the supervisor to detect any abnormally high temperature conditions in the system and initiate a reset command.

The MAX6316LUK29BX/V+T also includes a watchdog timer that can be used to monitor any failures in the system, such as a stuck program loop or a software crash. If the watchdog timer expires and detects a fault, it can initiate a reset to the system. The watchdog timer has an adjustable timeout period ranging from 1ms to 60s.

Conclusion

The MAX6316LUK29BX/V+T is a versatile, low-power supervisor designed specifically for mobile and portable electronic applications. It has a wide input voltage range, very low quiescent current consumption, and integrated system, voltage, and temperature monitoring functions. It is available in a 0.4mm × 0.4mm WLCSP package, making it suitable for the most space-constrained applications.
