TPS3824-25DBVRG4

Power management integrated circuits (PMICs) are important components that are used by devices to control their power supply for optimal performance and energy conservation. Supervisors form a key element of the PMIC family and offer the ability to monitor the status of various power supply components in the device, allowing for an array of power management features, such as reset and power sequencing. The TPS3824-25DBVRG4 from Texas Instruments is an example of a PMIC supervisor that has many application fields and a wide variety of features to provide reliable and efficient power management.

Features

The TPS3824-25DBVRG4 is a supervisor IC specifically designed to provide reset and supply monitoring functions. It is specifically designed to detect power supply voltages, so that it can monitor and control the supply voltage properly. It has a wide operational voltage range of 1.7 to 5.5V and is primarily suitable for use in battery-powered systems as it can detect a wide range of voltages. It is also able to detect when the voltage drops below a certain threshold, triggering its reset mechanism, this makes it suitable for industrial and automotive grade applications.

The IC also has an adjustable reset timeout and a push button reset input, for manual reset operations. It also offers the advantage of an output that is capable of sinking up to 3mA current. These features combined allows for this IC to be used to effectively control and monitor the power supply in a variety of applications, such as automotive, industrial, consumer, etc.

Application Fields

The TPS3824-25DBVRG4 is a highly versatile and reliable IC that can be used to effectively control the power supply in a variety of applications. One example of an application where this IC can be used is in systems where a combination of a primary and a secondary power supply needs to be monitored. The IC can be connected between the two supplies and the monitoring of both supplies can be enabled. This allows the reset threshold of one supply to be detected and when it is detected the reset of the other supply can be triggered.

Another example is an automotive ECU system, where the IC can be used to enable power sequencing. By connecting the TPS3824-25DBVRG4 to the various power supplies of the system, the reset and supply monitoring features can be used to ensure that the system operates in a secure, reliable and energy-efficient manner. The IC can also be used to monitor the voltage of the battery to ensure a safe working environment.

This IC can also be used in many industrial applications, such as in factory automation systems, where power supply monitoring is necessary to ensure that the system operates safely and reliably even in harsh environmental conditions. The IC can also be used in lighting control systems, power converters and data acquisition systems, where an output source is required for reset and power protection.

Working Principle

The working principle of the TPS3824-25DBVRG4 IC is based on the monitoring and control of two different power supplies. The IC is connected between the two supplies and can monitor the voltage level of each supply. If the voltage of the primary supply drops below or rises above the pre-set threshold level, the IC will trigger a reset of the other supply and turn it off. This enables the IC to regulate the power of the system according to the set parameters.

The IC also provides an adjustable reset timeout facility, which can be used to delay the reset of the secondary supply, allowing the system to remain in an active state until the primary supply have recovered. Moreover, the IC has a PUSH-button reset input, which allows the user to manually reset the system when necessary. The output of the IC can sink up to 3mA current and can be used to power other components of the system.

Conclusion

The TPS3824-25DBVRG4 from Texas Instrument is an example of a PMIC supervisor that has many application fields and a wide variety of features to provide reliable and efficient power management. Its strong reset and power monitoring capabilities, combined with its wide operating voltage range, makes it suitable for industrial, automotive and consumer applications. Its ability to detect voltage drops below or above a certain threshold, trigger a reset and its adjustable reset timing makes it an extremely useful IC for ensuring a reliable power supply for various electronic systems.
