Power management integrated circuits (PMICs) play an essential role in the functioning of most electronic systems. For example, they control power to multiple components, adjust output voltages, monitor supply voltages and regulate the current passing through a system. PMICs come in a variety of shapes and sizes to suit a variety of applications. Supervisors, also known as voltage supervisors, are a type of PMIC designed to detect events or changes in a system and protect it from errors.

The TPS3809I50MDBVREP is a high-performance voltage supervisor from Texas Instruments. With it, designers can quickly and easily incorporate fault detection, system reset and precise supply margins into their applications. It is ideal for use in harsh environments and has temperature range of -40℃ to 125℃.

Application Field

The TPS3809I50MDBVREP can be used in a variety of applications, such as automotive, avionics, industrial and portable, to name a few. It also has wide acceptance in the healthcare, communication and consumer electronics sectors. These applications require precise monitoring, isolation and accuracy, making it an ideal choice.

In automotive applications, the TPS3809I50MDBVREP can be used to provide over-voltage protection and enable systems such as navigation and infotainment. The supervisor is also suitable for use in powertrain and sensor applications, as it can monitor supply chain voltages and respond accordingly.

In avionics applications, the supervisor can be used to monitor system voltages and ensure aircraft safety. By monitoring the power supply throughout the system, the supervisor helps protect against faults or power supply instability.

In industrial applications, the supervisor can be used to monitor system voltage and provide a timely response should the voltage become too low. This is especially useful in applications such as motors and pumps, where low voltage could lead to system failure.

Finally, the TPS3809I50MDBVREP can be used in portable electronic applications. This includes devices such as tablets, smartphones and other handheld devices. By monitoring the system\'s power supply, this supervisor helps to provide a stable, reliable and efficient system.

Working Principle

The TPS3809I50MDBVREP is a low power voltage supervisor with an adjustable voltage monitor. It is designed to detect when the output voltage drops below a preset threshold and take action accordingly. It can be used to provide over-voltage protection, reset the system and ensure system reliability.

The supervisor functions by monitoring the output voltage of the power supply and comparing it to a set threshold. When the output voltage drops below the threshold, the TPS3809I50MDBVREP triggers a reset signal which shuts down the system. This reset signal can also be used to initiate a safety-shutdown procedure or start a system recovery process.

The supervisor is also designed to detect over-voltage conditions. When the output voltage goes above the threshold, the supervisor will monitor the voltage and alert the system of an over-voltage condition.

In addition, the supervisor can provide precise supply margins and fault detection using its wide operating range of -40℃ to 125℃. It also features low power consumption and high immunity to transients and noise.

The TPS3809I50MDBVREP is a high-performance voltage supervisor from Texas Instruments. It is ideal for applications in harsh environments, and can be used to detect events and provide reliable protection to systems such as automotive, avionics, industrial and portable. It is designed to detect when the output voltage drops below a preset threshold and take action accordingly, and can also monitor for over-voltage conditions and provide precise supply margins.
