PMIC (Power Management Integrated Circuits) are primarily used in the design and power management of electrical and electronic devices. Supervisors are one of the most popular components within the PMIC family, and offer features such as over-voltage protection, circuit reset and power on reset. One such device is the TPS3851H30EDRBT, a simple and cost-effective power supervisor with several optimized features. This article will explain the application field and working principle of the TPS3851H30EDRBT.

The TPS3851H30EDRBT is a low-power supervisor which monitors the voltage level on its input pin. This monitor voltage is compared with an internal threshold voltage, which can be adjusted via an external potentiometer, making this device an ideal solution for powering-up many applications. In terms of applications, the TPS3851H30EDRBT’s most common use is to monitor and protect against excessive voltage levels. For example, in applications such as batteries, solar cell controllers, or automotive systems, it can be used to prevent damage from external voltage spikes. Additionally, it can be used to generate power-on and power-off reset signals in many electronic applications.

To better understand the working principle of the TPS3851H30EDRBT, let’s take a look at its internal circuitry. The device contains two main components; an on-board regulator and an adjustable reference voltage generator. The regulator works by comparing the input voltage on its input pin to the reference voltage, to determine if the power-on/off reset state needs to be changed. The reference voltage generator can be adjusted via an external potentiometer, allowing users to set the device’s threshold voltage to more accurately set the device’s maximum allowable voltage. If the input voltage exceeds the preset threshold voltage, the device will shut down its output, preventing any further damage from occurring.

The device is incredibly easy to use, and can be quickly set up for use with a minimal number of components. In addition, it is also very flexible, as its adjustable reference voltage generator offers complete control over the device’s settings. This makes it an ideal power supervisor for many applications, as it can be easily adjusted to fit within any given system.

In conclusion, the TPS3851H30EDRBT is an effective and cost-effective solution for power management and circuit reset. By utilizing its adjustable reference voltage generator, the device can easily protect against excessive voltage levels, while simultaneously providing power-on and power-off reset signals. With its simple implementation and comprehensive features, the TPS3851H30EDRBT is the perfect choice for many applications which require reliable and accurate power management.
