Power management integrated circuits (PMICs) are important components of electronic systems, providing power to all the other components while controlling how it is delivered. A type of PMIC is a supervisor, and the MAX6832FXRD3+T is a supervisor specifically designed for battery-powered applications. This article will discuss the application field of the MAX6832FXRD3+T, as well as its working principle.

The MAX6832FXRD3+T was designed for applications powered by single-cell lithium-ion or lithium-polymer batteries. It offers a wide input voltage range from 1.8V to 5.5V, making it suitable for applications where the battery voltage is variable. The supervisor also integrates an accurate voltage monitor and low-drop-out (LDO) regulator, making it possible to monitor the battery voltage and regulate the power supply for the other components of the application. In addition, the MAX6832FXRD3+T provides several features that are beneficial for battery-powered applications. These features include a controlled shutdown, current limitation, and adjustable switching frequencies.

The MAX6832FXRD3+T is capable of monitoring two voltages. The first is the battery voltage, which is monitored using an accurate voltage monitor. This voltage monitor can tolerate voltage excursions outside its operating range and will alert the microcontroller if the battery voltage reaches a predetermined level. The second voltage that can be monitored is the system output voltage, which is regulated using the integrated LDO regulator. The LDO regulator can provide up to 200mA of current and has a 0.7V dropout voltage, making it suitable for powering low-power devices.

In addition to monitoring voltages, the MAX6832FXRD3+T also provides several features for protecting the battery and system. These features include current limitation, controlled shutdown, and adjustable switching frequency. The current limitation feature limits the amount of current that can flow from the battery to the system, protecting it from high-current spikes. The controlled shutdown feature can be configured to shut down the system upon detecting a low-battery condition. Finally, the adjustable switching frequency allows the supervisor to operate at a frequency that is suitable for the application, reducing power consumption and extending battery life.

The MAX6832FXRD3+T is an ideal supervisor for battery-powered applications. Its ability to monitor two voltages, provide current limitation, controlled shutdown, and adjustable switching frequency ensures that the system will maintain a safe operating environment. This allows for reliable operation for applications that are powered by single-cell lithium-ion or lithium-polymer batteries.
