PMIC - Supervisors such as the X5165P serve many important purposes that keep the system running efficiently by preventing undesired output behavior. Most supervisors contain a supervisory circuit, a factory-configured reset circuit and a supply voltage monitor. The X5165P, manufactured by STMicroelectronics, is a system supervisor and power-on reset generator specifically designed for power-supply monitoring and system reset protection functions.

The supervisor monitors the system’s power supply and provides a reset signal if the system fails to meet user-defined reset thresholds. In addition, the X5165P provides an adjustable supply voltage monitor with power-on reset (POR), power-fail warning (PFW) and brown-out reset (BOR) features. The adjustable features allow users to set the desired voltage monitored, the reset threshold and 5 reset output types to suit specific needs. The supervisor also includes an interrupt signal which can be used for warning or for power-fail signal.

The X5165P’s applications range from industrial to consumer electronics. It is used in products such as automotive infotainment systems, gaming consoles, LAN switches, and set top boxes. By ensuring the system can reset after a power failure, it preserves system integrity and reliability.

The X5165P is an industrial control device, whose operation is based on the principles of electrical current and voltage. The main integrated circuits (ICs) in the X5165P are voltage regulators, transistors, diodes and resistors. The electrical signals are generated and manipulated using these components.

The X5165P contains a supervisory circuit which monitors the supply voltage. This signal is compared to a preset reference voltage, whose value is set by an external resistor. If the supply voltage exceeds the preset threshold, a reset signal is generated. The reset signals are configurable and can be set to either active high or active low.

It also includes a POR circuit. This circuit will detect if the power supply is below a preset threshold. When this happens, the POR circuit will trigger a reset signal. This reset signal will cause the system to reset and remain in reset state until the power supply is above the threshold again. The POR circuit also monitors the power supply input voltage and warns the user if the input voltage is outside the threshold.

The X5165P also contains a BOR circuit. The BOR circuit monitors the supply voltage and sends out a reset signal if it senses that the power supply is below a preset threshold. This reset signal will cause the system to reset until the power supply is above the threshold again. The BOR circuit also monitors the power supply input voltage and warns the user if the input voltage is below the threshold.

Finally, the X5165P contains a PFW circuit. This circuit monitors the power supply input voltage and sends out a warning signal if the input voltage is outside the preset threshold. The warning signal is used to alert the user that the power supply is not functioning properly. This allows the user to take corrective action before the power supply fails completely and results in a system crash.

The X5165P is a powerful system supervisor and power-on reset generator designed for a wide range of applications. Its combination of adjustable settings, POR, PFW and BOR features make it well suited to use in industrial systems, consumer electronics and other applications. With these features, the X5165P ensures a reliable, long-term and fail-safe operation of the system.
