Furthermore, it is able to monitor output power and return it to normal operation if it falls below the predefined threshold. The device also offers several safety features such as thermal protection, as well as adjustable delay times for reset operation.

III. Working Principle

The TPS3620-50DGKTG4 works by monitoring the power supply voltage, system reset, and power supply overvoltage conditions. The device has integrated overvoltage protection (OVP) and comparator with adjustable reset level, which offer system monitoring for easy and reliable battery operation.

Moreover, the TPS3620-50DGKTG4 monitors the power supply input voltage, and issues a reset signal if it is outside the specified threshold. The device supports an adjustable voltage window that can be set according to the desired reset levels, as well as an adjustable current-limit threshold.

In order to ensure reliable system operation, the TPS3620-50DGKTG4 also offers a number of power supply protection features; these include output voltage-regulation control, overvoltage protection, and thermal protection. Moreover, the device supports an adjustable power-down delay time, which can be adjusted based on the application needs.

IV. Features

The TPS3620-50DGKTG4 offers a number of features that can provide reliable system protection and monitoring. It has an adjustable input voltage window, adjustable reset level, adjustable current-limit threshold, output voltage-regulation control, adjustable power-down delay time, and thermal protection. Additionally, it has an active-low reset signal and an active-low power-down signal. The device also supports an enable input, which allows the system to enable/disable the device in order to maintain reliable operation.

V. Conclusion

In conclusion, the TPS3620-50DGKTG4 is a PMIC supervisors solution from Texas Instruments. It provides system protection and supply monitoring for many power-supply designs.
