TPS2042BEVM-293 Introduction

In the realm of power distribution systems, it is of utmost importance to effectively manage heavy capacitive loads and potential short circuits. The TPS2042B power distribution switch is used in this scenario. This device has been specifically designed to meet the needs of demanding applications by integrating multiple power switches into a single package. The purpose of this comprehensive guide is to give you a detailed overview and understanding of the TPS2042BDGNR. It will cover its features, operation, and application.

Overview of the TPS2042BDGNR Power Distribution Switch

The power distribution switch TPS2042BDGNR was created for demanding applications. It is efficient and compact since it combines several power switches into a single unit. This convergence streamlines production, boosts dependability, and enables fine-grained control over power channels. Overall, it offers a thorough and effective answer for power management in a variety of systems.

TPS2042BEVM-293 Features and Functionality

N-channel MOSFET power switches measuring 70 m are included in the TPS2042BDGNR power distribution switch. These switches make it possible for systems that need several switches to distribute electricity effectively. Each switch is input-controlled by the logic, enabling seamless integration into a variety of applications. The device has an in-built charge pump that enables controlled rise and fall times of the power switch in order to reduce current surges while switching.

● Flexible Power Supply

The TPS2042BDGNR’s adaptability in terms of power supply requirements is a noteworthy benefit. It can function properly with power sources as low as 2.7 volts. Due to its adaptability, it may be used with a variety of voltage combinations and is compatible with a wide range of power distribution systems.

● Current Limit and Protection

The TPS2042BDGNR uses a clever current-limit device to guarantee safe operation even in difficult circumstances. When the output load goes over the current-limit threshold or a short circuit happens, the device changes to a constant-current mode. This effectively pulls the overcurrent (OCx) logic output low and restricts the output current to a safe level. By doing this, it safeguards the system from possible harm brought on by excessive current flow.

● Thermal Protection

The TPS2042BDGNR has an integrated thermal protection circuit for instances where frequent heavy overloads or short circuits result in increased power dissipation. To avoid any damage to the device, this circuit starts a shutdown process and checks the junction temperature. The switch automatically recovers and resumes normal functioning as soon as the junction temperature has decreased to a safe level. To increase safety and reliability, the internal circuitry makes sure the switch is off until a valid input voltage is found.

Application and Evaluation Board

The TPS2042BDGNR is a power management evaluation board that is specifically created to support a variety of power distribution applications. It provides a dependable and effective way to manage power distribution systems with its normal current-limit setting of 1 A.

Functionality and Operation

Each switch is managed by the TPS2042BDGNR through a logic enable input. This enables autonomous control of each power switch’s state, enabling fine management of power channels based on particular needs.

The TPS2042BDGNR has an in-built charge pump to prevent current surges and ensure smooth switching transitions. The rise and fall periods of the power switches are tightly regulated by the charge pump. It significantly lessens the effects of current spikes that may happen during switching operations by controlling these timings.

The internal charge pump streamlines the design process by eliminating the requirement for external components. Its goal is to improve the characteristics of power switching, ensuring dependable and effective power distribution. The TPS2042BDGNR avoids any disturbances or voltage spikes that could adversely affect the system or linked components by controlling rise and fall timings.

● Flexible Power Supply

The power distribution switch TPS2042BDGNR demonstrates the ability to run on power sources as low as 2.7 V. The switch can suit a variety of power distribution systems because of its versatility in voltage compatibility. The TPS2042BDGNR may smoothly integrate into a variety of applications, offering adaptability and ease regardless of the particular voltage needs.

The benefit of this versatility is that it can accommodate a variety of power distribution arrangements. The TPS2042BDGNR’s capacity to handle lower voltage sources assures compatibility and dependable performance in various contexts, whether it be industrial, automotive, or other electrical systems.

● Current Limit and Protection

To ensure safe operation, the TPS2042BDGNR has a sophisticated current-limit mechanism. The device quickly switches to constant-current mode when the output load exceeds the current-limit threshold or a short circuit occurs. By limiting the output current to a reasonable level, this mode guards against possible harm to the system or associated components.

The overcurrent (OCx) logic output of the TPS2042BDGNR is used to enable this current limiting. By alerting the user to an excessive current flow, this output is essential to protecting the system from damage. The TPS2042BDGNR monitors for overcurrent circumstances and takes preventative action to safeguard the system and preserve its integrity.

● Thermal Protection

A built-in thermal protection circuit allows the TPS2042BDGNR to operate reliably even in challenging conditions. This circuit actively monitors the junction temperature of the power distribution switch. The thermal protection mechanism kicks in when severe overloads or short circuits increase power dissipation and raise the junction temperature to potentially hazardous levels.

The thermal protection circuit starts a shutdown procedure when the junction temperature rises above the safe level. This step protects the connected system and the device from further harm. The TPS2042BDGNR doesn’t turn on until the junction temperature has sufficiently decreased in order to maintain safety.

The thermal protection mechanism has an automatic recovery capability. The device immediately resumes normal operation once it has cooled down to a safe level. The power distribution switch’s convenience and dependability are improved by eliminating the need for manual intervention.

In conclusion, the TPS2042BDGNR power distribution switch delivers robust thermal protection, adjustable current-limiting features, and power supply compatibility. It is the best option for demanding applications since these features assure safe and dependable operation in diverse power distribution systems.


In conclusion, the TPS2042BDGNR Power Distribution Switch stands as a reliable, efficient, and safe solution for effectively managing heavy loads and short circuits. Its integrated power switches and compatibility with low-voltage supplies offer exceptional flexibility across a range of applications. With its intelligent current-limit mechanism and overcurrent protection, system safety is ensured, while the built-in thermal protection circuit guards against damage from overloads. In diverse settings, the TPS2042BDGNR proves to be a fitting choice for power distribution requirements.
