PMIC- Supervisors

PMIC, an acronym for power management integrated circuit, is an important tool used in power management applications. Supervisors, a type of PMIC, provide multiple functions, such as monitoring battery voltage, alerting users in case of power failure, and keeping track of battery power and performance. The MAX6383XR29D2+T is a supervisor suitable for use in battery-operated products.

Applications

The MAX6383XR29D2+T is a versatile, low-power supervisor, design for batteries-operated applications. Its features include a wide input-voltage range (1.4V to 5.5V) tolerance for a range of battery chemistries, and a built-in low-voltage-detection (LVD) circuit with programmable threshold and reset output levels. Its power-fail input and reset output provide an easy way to check the battery’s voltage, eliminating the need for additional components.

The MAX6383XR29D2+T can be used to monitor and protect external power sources and peripherals, as well as to give additional system-level protection. Its features make it a great choice for battery-powered applications, such as portable medical or gaming devices, or for automotive and industrial applications.

Working Principle

The MAX6383XR29D2+T operates by constantly monitoring the voltage of the battery and providing an alert when the voltage drops below a certain level. It is designed to alert the user and protect the battery from damage, either by automatically disconnecting it from the circuit, or by signaling the system to initiate a proper battery protection procedure. In addition, it also offers a reset output that signals the system when the battery voltage is back to an acceptable level.

The MAX6383XR29D2+T is unique among other supervisors, as it utilizes an advanced algorithm to continuously monitor the battery’s voltage and provide accurate low-voltage-detection thresholds. This allows the supervisor to automatically adjust the threshold of operation, thus ensuring that the device is always protected, even when the battery’s voltage is constantly changing. The MAX6383XR29D2+T also includes an internal watchdog timer that can be used to restart the system, in case the system hangs or crashes. This makes it an ideal choice for monitoring the voltage of both primary and backup batteries.

Advantages

The MAX6383XR29D2+T supervisor offers a range of advantages for power management applications. It is small in size, low in power consumption and low in cost, making it highly suitable for a range of equipment, whether stationary or mobile. Its wide voltage tolerance means that it can be used with a variety of batteries, from alkaline, to lithium-ion, to lithium-polymer.

The MAX6383XR29D2+T is also highly versatile. Not only is it capable of monitoring a wide range of batteries, but it can also be used to connect multiple power sources and peripherals. Furthermore, its integrated reset output ensures that the system is protected, and that it is able to restart quickly in case of a power failure.

Finally, the MAX6383XR29D2+T is easy to use and configure. Its pin-selectable features allow for fast and easy configuration, making it an ideal choice for rapid prototyping. Its low power consumption also makes it an attractive choice for a range of applications in need of power management.

Conclusion

The MAX6383XR29D2+T is a versatile, low-power supervisor, suitable for use in battery-powered applications. It offers a wide input-voltage tolerance, a reset output, an integrated watchdog timer, and an advanced algorithm to periodically adjust thresholds. Its small size, low power consumption, and easy configuration make it a great choice for a range of power-management applications.
