X5168S8I-4.5A Application Field and Working Principle

PMIC - Supervisors are an important component of every circuit board and are used to monitor and control the power distribution in circuit boards. The X5168S8I-4.5A is a supervisor IC which has a wide range of applications in electronic circuits. This article will discuss the application field and the working principle of this IC.

Application Field

The X5168S8I-4.5A supervisor IC can be used in a variety of circuits and systems such as embedded systems, gate drivers, LED drivers, power management units, LED monitors, PC motherboards, and many more. This makes it an ideal choice for a wide range of applications. It can also be used to monitor the current and voltage conditions at various points in a circuit.

This IC is also used to monitor and protect the power system against various types of power supply faults and can be used to control the supply voltages. It can also be used as a power-on reset (POR) to reset the system at power-up or as a brownout detector to detect when the voltage drops too low. It is also used as a watchdog timer to periodically check the system health.

Working Principle

The X5168S8I-4.5A supervisor IC contains an alarm comparator, a delay timer, an over-voltage detector, an under-voltage detector, and a reset control logic. The purpose of the alarm comparator is to compare the voltage within specified limits and generate an alarm output if the voltage goes outside of those limits. The delay timer is used to delay the alarm output for a short period of time in order to reduce false alarms. The over-voltage detector monitors the system’s voltage and will assert a reset output if the voltage rises too high. The under-voltage detector monitors the system’s voltage and will assert a reset output if the voltage drops too low. The reset control logic will assert a reset signal if any of the above conditions are met. This IC also has an adjustable voltage range, allowing you to specify the upper and lower limits of the monitored voltage.

As mentioned earlier, this supervisor IC is an ideal choice for a wide range of applications in various electrical circuits. It is easy to use and provides reliable protection against various power supply faults. Additionally, it is a cost-effective solution and can be easily implemented into existing circuit boards.
