The TPS3618-50DGKT PMIC Supervisor is designed for use in a wide variety of applications. The primary applications of the device include:* Automotive systems: The device is ideally suited to automotive systems because of its wide operating temperature range and its ability to provide power supply sequencing during power up/shutdown and fault protection during operation.* Industrial systems: The device is ideal for industrial systems due to its wide operating temperature range and its ability to provide power supply sequencing during power up/shutdown and fault protection during operation.* Home theatre systems: The device provides the power supply sequencing and fault protection required for the various components of home theatre systems.* Computer systems: The device is well-suited for PC motherboards because it provides the power supply sequencing and fault protection required for the various components.

Working Principles

The TPS3618-50DGKT PMIC Supervisor is designed to provide power supply sequencing and fault protection for up to four external supplies. It is primarily used to increase the reliability and safety of power systems.The TPS3618-50DGKT PMIC Supervisor works by monitoring the voltages of the external power supplies and ensuring that they are within the target range. If any of the external supplies deviate from the target values, the TPS3618-50DGKT PMIC Supervisor will automatically place the system in fault mode and disable the external power supplies. The TPS3618-50DGKT PMIC Supervisor is also used for power supply sequencing. By properly sequencing the power supply rail voltages, it can ensure that the system is always powered in the proper sequence. This increases system reliability and prevents system damage due to incorrect power supply rail voltages. In addition to power supply sequencing and fault protection, the TPS3618-50DGKT PMIC Supervisor also provides two low-drop-out (LDO) voltage regulators. The two LDOs can provide different voltages for various system components. The LDOs also provide the necessary current limits for the different system components.

Conclusion

The TPS3618-50DGKT PMIC Supervisor is a power management integrated circuit specifically designed for use in systems with multiple power supplies. It provides power supply sequencing and fault protection for up to four external supplies. It also has wide operating temperature range and two low-drop-out (LDO) voltage regulators for various system components. The device is suitable for automotive, industrial, home theatre and computer systems. The TPS3618-50DGKT PMIC Supervisor is an ideal solution for reliable and safe power systems. It ensures that the external power supplies remain within the target range and properly sequences them, providing system reliability and integrity. The two LDOs provide the necessary voltage and current levels for system components.
