Power management integrated circuits (PMICs) are customized circuits that allow the processor, peripheral components, and other electronics to share the same power supply. Supervisors are a class of PMICs that monitor the power supply voltage and its current to prevent damage from overloads. The MAX6348XR40-T is a supervisor IC that features low quiescent current, allowing it to be used effectively in a wide range of applications. In this article, we\'ll take a look at the features and working principle of the MAX6348XR40-T, and explore its application field.

Features

The MAX6348XR40-T is a low quiescent current supervisor IC that monitors the power supply voltage and current of digital systems. It features a wide input voltage range of 2.9V-5.5V, making it suitable for 3.3V, 4.2V, 5V, and 12V systems. It can detect supply voltages down to 1.450V, and has a 20ns response time, improving its efficiency over other supervisors.

The MAX6348XR40-T also features an adjustable reset output threshold, allowing users to customize the reset voltage. This ensures that the supervised system can operate safely and reliably, as it won\'t enagage the reset until the proper reset threshold is met.

The IC includes an active-low reset output and an active-low interrupt output, allowing the evaluation of the power supply without having to manually check the supervisor. It also includes an internal watchdog timer, which provides an additional layer of safety for the system by setting a timeout for all operations.

Working Principle

The MAX6348XR40-T works by monitoring the power supply voltage and current of the system. It has an open-drain output, meaning that it can be connected to other UNL462X devices in the circuit. This allows the supervisor to detect the supply voltage and current of any circuit connected to the same UNL462X family.

The MAX6348XR40-T also has a built-in watchdog timer that sets a timeout for all operations in the circuit. The watchdog timer will reset the system and trigger an interrupt output if the timeout is exceeded. This ensures that the system won\'t suffer from any malfunction and can operate safely and reliably.

Applications

The MAX6348XR40-T is a versatile supervisor IC that can be used in a wide range of applications. It is a suitable fit for microcontroller-based systems, as well as for embedded systems in industrial and consumer products. It can also be used for battery-powered systems, as it consumes a low quiescent current and can detect supply voltages down to 1.450V.

The MAX6348XR40-T can also be used in embedded security systems, as it has an adjustable reset output threshold and an internal watchdog timer. This makes it an ideal choice for applications where safety and reliability are of utmost importance.

The MAX6348XR40-T can also be used in avionics and medical systems. Its low quiescent current and wide input voltage range make it suitable for these applications. Additionally, its adjustable reset output threshold and watchdog timer ensure that the monitored systems operate safely and reliably.

Conclusion

The MAX6348XR40-T is a low quiescent current supervisor IC that monitors the power supply of a system. It features a wide input voltage range of 2.9V-5.5V, allowing it to be used effectively in a range of applications. Additionally, it has an adjustable reset output threshold and an internal watchdog timer, allowing it to be used in safety-critical systems. The MAX6348XR40-T is an ideal choice for embedded systems in industrial and consumer products, avionics systems, and medical systems.
