Power management ICs (PMICs) are integrated circuits used in a variety of electronic devices that are meant to manage the power supply and reduce the overall power consumption. They are used in smartphones, tablets, laptops, embedded systems, consumer electronics, and automotive applications. PMICs can operate in different power management scenarios, such as switching mode, linear voltage regulation, and battery management. Among different PMICs, Supervisors are the integrated circuits used to supervise the power supply management of the system.

The LM8364BALMFX20/NOPB is a highly integrated Supervisors device which is specially designed to protect a 3.3V system from over-voltage. This logic family device offers open-drain, active-low reset output and a low-voltage threshold reset that operates at a nominal voltage of 3.00V with a reset timeout of 1.5s (adjustable).

This integrated device combines two independently programmable supervisory circuits, one for power up and one for power down. It is used to provide system voltage monitoring and reset to protect from accidental programming, hardware misconfiguration and process variation. The device also offers an open-drain, active-low manual reset input and a low-voltage threshold reset that operates at a nominal voltage of 3.00V with a reset timeout of 1.5s (adjustable). It is available in an 8-pin SOIC or DFN package.

The LM8364BALMFX20/NOPB is widely used in applications where temperature drift, power transients and process variations must be monitored and reset. These applications include computers, tablets, industrial control systems, instrumentation, robotics and communications systems.

The LM8364BALMFX20/NOPB Supervisors works by providing an open-drain bus to pull low the reset pin when over-voltage is detected. The voltage threshold is VTH1 and the reset timeout is 1.5s. The device also provides an open-drain manual reset input, which is enabled by pulling the MR pin low. When the manual reset input is enabled, the reset pin is forced low.

The LM8364BALMFX20/NOPB can be combined with other over-voltage protection components such as TVS diodes and fet-based circuit breakers for redundant over-voltage protection and reliable reset of the system. It also works well in combination with other power-supply and over-voltage protection solutions, such as buck and boost converters, active voltage samplers, etc.

The LM8364BALMFX20/NOPB Supervisors can be applied in a broad range of applications requiring over-voltage protection and reliable reset, including computers, tablets, industrial control systems, instrumentation, robotics, and communications systems. In these applications, it provides effective, reliable over-voltage protection and reset, with minimal power consumption and a small footprint.
