PMIC - Supervisors are devices which are traditionally utilized to allow a power system to achieve higher peak currents, higher levels of accuracy and reliability, and an overall more efficient operation than what is possible without one. The TPS3820-50DBVT is one of the most powerful and versatile PMIC - Supervisors available and is used in a wide variety of applications, including power management and protection of sensitive circuit components on various electronic devices. This article will discuss the application field and working principle of the TPS3820-50DBVT, and explain why it is such a highly regarded component.

The TPS3820-50DBVT is a highly effective voltage supervisor, capable of providing power-on reset and outputting reset signals for microcontrollers and other integrated circuits. It is well suited for harsh industrial, automotive and telecom applications. With a wide operating temperature range of -40°C to +125°C and an adjustable reset threshold voltage ranging from 1.2V to 6.5V, the TPS3820-50DBVT can be used for a variety of applications.

This device is sometimes referred to as a resettable fuse. It monitors the voltage on the power supply and output voltage signals accordingly. If the output voltage drops below the reset threshold voltage, the TPS3820-50DBVT will output a reset signal to reset the microcontroller or other ICs. This is beneficial in cases where a power surge could lead to a malfunction of the system. This makes it a very useful component in applications where power surges are expected, such as automotive and industrial applications.

The TPS3820-50DBVT has a variety of features designed to make it one of the most versatile supervisors available. It is designed to be compatible with a wide variety of microcontroller and ICs, with reset active high or low strategies. It also has adjustable time delays and an active low power good output to indicate when a reset occurs.

The TPS3820-50DBVT also integrates two monitoring circuits. The first monitor is the Primary Undervoltage monitor which continuously monitors the reset level of the power supply. If the power supply drops below the reset threshold, the Primary Undervoltage monitor will immediately output a reset signal and place the system in a safe state. The second monitor is the Secondary Overvoltage monitor which continuously monitors the voltage output at the device’s output pins. The Secondary Overvoltage monitor will also output a reset signal if the voltage exceeds the specified threshold.

The TPS3820-50DBVT also has a built-in watchdog timer which helps detect and recover from power supply faults. If the voltage continues to drop below the reset threshold for a set amount of time, the TPS3820-50DBVT will output a reset signal and allow the system to reset and come back online. This prevents the system from crashing due to power failures or malformed output signals.

The TPS3820-50DBVT is a very versatile device and can be used in a wide variety of applications. Its combination of accurate and reliable power monitoring, with built-in features such as a watchdog timer, make it an ideal choice for many designs. Its wide operating temperature range, adjustable reset threshold voltage, and compatibility with various microcontroller and ICs make it a highly versatile component.
