PMIC - Supervisors, the TPS3820-33DBVTG4, is a regulated power supply solution designed to work in a variety of applications, including embedded systems and internet of things (IoT), automotive and industrial applications. Its wide operating temperature range and low quiescent current make it suitable for both portable and stationary applications.

The TPS3820-33DBVTG4 monitor the power supply voltage in order to maintain system stability and an optimal operational environment. The integrated supervisor has two independent power supply inputs, one of which provides power to the device. The other is a control input that tells the device when to activate and deactivate, such as when the system is under- or over-voltage. Also, the TPS3820-33DBVTG4 has a monitoring comparator that compares the main power supply voltage to a preset voltage threshold. When the voltage falls below the threshold, the comparator triggers an active reset, which forces a system reset. This helps to prevent data loss or system malfunctions caused by deviations in the power supply voltage.

The watchdog functionality of the TPS3820-33DBVTG4 is also important, as it detects system failures and takes action to maintain system stability. The integrated watchdog monitors the software program executing within the system, and if it detects a system failure or error, it triggers a reset signal to the microcontroller or other system components. This helps to ensure that the system always operates correctly and does not cause any damage to the system or components.

The TPS3820-33DBVTG4 also protects the system from over-voltage transients. This protection is achieved through an over-voltage detection comparator that compares the input power supply voltage to a preset upper limit. If the voltage exceeds the upper limit, the comparator triggers a reset signal that can either shut down the system or initiate power sequencing. This ensures that the system operates within its optimum voltage range, even in the presence of transient over-voltages.

In addition to these features, the TPS3820-33DBVTG4 also includes an early warning system (EWS) to detect over- and under-voltages. The EWS works by continuously monitoring the system voltage and comparing it to a preset voltage window. If the voltage falls outside the window, the EWS will generate an alarm signal that can be used to warn the system administrator of a potential problem. This can help to prevent data loss, system failure, and unnecessary power cycle life.

The TPS3820-33DBVTG4 is an ideal solution for protecting embedded systems and IoT, automotive and industrial applications from power supply instability, over-voltage transients, and system failure or errors. Its multiple monitoring and reset functions work together to ensure that the system always operates within its optimal voltage range, keeping it running reliably for extended periods of time.
