TPS3813J25DBVR

PMIC - Supervisors are a type of integrated circuit (IC) designed to provide power management, monitoring and protection for the power supply to a variety of electronics including computers, servers and mobile devices. The TPS3813J25DBVR is a supervisor IC designed for high temperature environments, making it well suited for automotive and industrial applications.

The TPS3813J25DBVR provides superior protection against overvoltages and undershoots with a wide range of features. It features an adjustable power supply supervisor that provides an adjustable voltage trip point. The supervisor monitors a single +3.3V power supply, but has the ability to also monitor two resistor-divided external supply lines. It also has a reset timer that delays the assertion of the reset signal to allow time for power supply stabilization.

Undervoltage protection is provided for both the regulated voltage and the resistor-divided external supply lines. The TPS3813J25DBVR also includes an adjustable hysteresis that allow it to be used in applications with large load transient and power supply variability. For example, when connected to an external device that draws large current such as a stepper motor, the hysteresis will help ensure stability by reducing the risk of false triggering of the reset signal.

The TPS3813J25DBVR also includes several other features such as a low power sleep mode and separate inputs for both active-high and active-low reset. This supervisor IC also includes features to reduce quiescent current, making it well suited for battery powered applications. Additionally, its wide operating temperature range (-40°C to +125°C) makes it suitable for a variety of harsh environments.

The TPS3813J25DBVR is well suited for a variety of automotive and industrial applications. It can be used in vehicle battery monitoring systems to monitor both the battery voltage and the alternator voltage. It can also be used in industrial control systems, providing monitoring and protection for the power supply to devices such as motors, pumps and relays.

In addition to its application field, the TPS3813J25DBVR also has a working principle that is easy to understand. It monitors the input voltage and provides an output signal if the voltage exceeds, falls below, or fails to exceed a preset threshold. If a fault is detected, the output signal is sent to the system, activating the reset signal and initiating a power-down sequence.

The TPS3813J25DBVR supervisor IC is an ideal solution for a variety of electronics applications, providing power management, monitoring and protection. Its adjustable voltage trip point and wide operating temperature range make it suitable for harsh environments, and its low power sleep mode and additional features make it an ideal choice for automotive and industrial applications.
