The IC can also use an internal voltage reference, or an external voltage reference to monitor the voltage. It also has additional features such as external power supply monitoring, reboot function, adjustable reboot voltage, adjustable power loss voltage, time constant, etc.
The TPS3823 also features a unique watchdog function that monitors the health of the system to ensure that it is functioning properly. When the watchdog detects a system failure, it triggers a reset signal to restart the system. The watchdog is maintained by a separate timer that can be set at intervals by an external voltage.
In the event of a system power loss or blackout, the standalone watchdog function will ensure that there is enough time to reboot the system and protect the data in the memory from being lost. This makes the IC ideal for applications requiring high reliability, such as industrial automation, medical devices, and more.
In addition, the TPS3823 features step-down accuracy up to 2.1V and restart voltage as low as 1.7V, which allows the IC to operate in lower voltage applications. It also features ultra-low operating currents down to 2uA, which allows it to be used in high-efficiency power systems.
The TPS3823 is available in two different packages, SOT23-5 and DFN-8, which provide more options for different applications. These features make this IC a very powerful and flexible voltage monitoring solution for a wide variety of applications.
