Evaluation and Demonstration Boards and Kits offer a comprehensive set of tools to quickly and easily analyze the performance and features of various components used in various applications, such as communication systems, medical devices, Test and Measurement and Automation and Control systems. TPS23753AEVM-004 (Evaluation Module) is one such product which is designed to demonstrate the design capabilities and features of the TPS23753 device, a low-power, standby utility switch which protects the system against undesirable power transients from a variety of sources. The application field and working principle of this product are as follows.

Application Field

The TPS23753AEVM-004 is best used in the following applications:

• System standby supply switches: This module can be used in systems where the power supply switch is required to reduce power consumption in standby, sleep, or shut-down states.
• Desktop computers, servers, and workstations: The TPS23753AEVM-004 can be used to provide protection against undesirable power transients and load protection when switching between different power sources.
• Telecommunication systems: The module can also be used in telecommunication systems which require protection against transients and a high cycling reliability.
• Industrial controllers, point-of-sale machines, medical equipments, automotive: Apart from the above-mentioned applications for which the device was specifically designed, the module can also be used in industrial controllers and point-of-sale systems, medical equipments, and automotive applications.

Working Principle

The TPS23753AEVM-004 is basically an electronic switch which is designed to connect and disconnect power supply lines from the system. It consists of a control board with a PIC microcontroller, an input power supply block, an output load block, and the TPS23753 device. The main objective of this evaluation module is to demonstrate the capabilities and features of the TPS23753 device, such as low-power standby current, power switch protection against transients, and high cycling reliability.

The module works on a simple principle: when the system is powered up, the microcontroller enables the TPS23753 device, which in turn activates the power switch. This switch then connects the input power supply and the output load, allowing the power to be supplied to the system. When the system is in standby mode or shut-down state, the microcontroller disables the TPS23753 device, thereby disconnecting the power source from the system.

Additionally, the TPS23753AEVM-004 has several features which make it a superior device. These features are as follows:

• Protection from transients: The device is designed with overvoltage and current-protection circuitry, which helps protect the system from various transients.
• High cycling reliability: The device is capable of performing as many as 20000 cycles without any significant performance degradation.
• Low power dissipated: The device operates at very low levels of power consumption, making it an ideal choice for applications where power efficiency is a critical factor.
• Low power consumption in standby: The device is designed to consume minimal power in standby mode, making it ideal for applications where power consumption needs to be minimized.

Overall, the TPS23753AEVM-004 evaluation module provides a comprehensive demonstration of the features and design capabilities of the TPS23753 device. With its low power consumption, protection from transients, and high cycling reliability, the device is ideal for a variety of applications which require protection and reliability during switching operations.
