Introduction
The TPS3620-50DGKR is a PMIC - Supervisors, a device that works as a supervisor in power management in embedded systems. It is designed to monitor the power supply voltages and control the power on reset and the power off reset. This device provides protection against overvoltage, undervoltage, and reverse current protection. It also provides supply voltage debounce, power-on reset, and power-off reset with a fixed threshold and fault detection.
Application Fields
The TPS3620-50DGKR has a wide range of applications in many industries. It can be used in industrial, automotive, and communications applications. In industrial applications, it can be used for power supply sequencing, power supply sequencing supervision, and overcurrent protection. In automotive applications, it can be used for power supply monitoring, power-on reset, and fault monitoring. In communications applications, it can be used for power supply monitoring and fault detection. The device also has small-signal protection and current-sense protection.Working Principle
The TPS3620-50DGKR works by using a feedback loop. It constantly checks the voltage across the power supply to make sure it is within the specified voltage range. When the voltage is outside of the set range, a warning signal is sent to the processor to let it know the power supply needs to be shut off. The device then activates the power-on reset and power-off reset signals, turning off the power supply and preventing any damage to the system.The device also includes a current-sense protection circuit, which monitors the amount of current flowing through it. If the current exceeds the set limit, the device activates the power-on reset and power-off reset signals, preventing possible damage to the system.The device is also used in power sequencing applications, where it is responsible for sequencing the power supply on and off in the correct sequence. It can also detect any faults in the power supply and activate the power-on reset and power-off reset signals, preventing any damage caused by incorrect power sequences.The device has a low operating power consumption, making it ideal for battery powered applications. It also features a fixed reset threshold and fault detection, making it reliable in most applications.Conclusion
In conclusion, the TPS3620-50DGKR is a PMIC - Supervisors device that provides power supply monitoring, power-on reset, power-off reset, current-sense protection, and power sequencing applications. It has a wide range of applications in industrial, automotive, and communications applications. The device also has a low operating power consumption and a fixed reset threshold and fault detection. It is an ideal choice for reliable power management in embedded systems.
