PMIC - Supervisors are integral in keeping a device working as intended, and the industry-standard TPS3851H18EQDRBRQ1 is an excellent example. With a host of features and a small size, the TPS3851 is a great choice for supervisors in a variety of applications. In this article, we\'ll explore a few of the potential applications of the TPS3851 as well as how it works and what it can, and cannot, do.

The TPS3851 is a precision, low-power, ultra-low-voltage supervisor with an integrated low-voltage reset. It\'s designed to monitor power pins and if power dips below an adjustable threshold, the IC can automatically lower the output voltage. This can be beneficial in a number of scenarios and is especially suitable for battery-operated environments.

The TPS3851 has both a reset signal and a power-fail (active low) signal. The reset signal is triggered when the voltage is below the set threshold; the power-fail signal is set when the voltage is above the threshold.

The TPS3851\'s small size and its wide range of features make it a great choice for applications where its reset and power-fail signals would be regularly called upon. This could include automotive applications, telecommunication systems, test equipment, and any other application where a reset may be necessary in a power failure scenario.

In addition to its reset and power-fail signals, the TPS3851 also offers two timeout functions. These allow for a timed reset or power-fail signal to be issued; the duration is adjustable. This allows for even more flexibility in the design of a supervisor-protected system, allowing for a reset or power-fail signal to be issued at predetermined intervals.

When it comes to the working principle of the TPS3851, it all hinges on the precision, low-power supply that it offers. This is where the chip can be adjusted to a number of different voltage levels, allowing the reset and power-fail signals to be triggered at the appropriate levels.

The TPS3851 also offers under-voltage detection, which works by monitoring the voltage inputs and comparing them to a reference. If the reference is exceeded, then a reset signal is issued to protect the device from any potential damage or malfunction.

Finally, the TPS3851H18EQDRBRQ1 also offers an option for current-limited power-on reset (CLRx) and electroluminescence (EL). CLRx allows for a longer reset period and EL offers an improved reset reliability and accuracy.

As you can see, the TPS3851H18EQDRBRQ1 is a great choice of PMIC - Supervisors for any applications where reset and power-fail signals are needed. With its low power consumption and its flexibility, the TPS3851 cannot only protect a system from power-related issues but also allow for more customised protection scenarios as well.
