Evaluation and Demonstration Boards and Kits – TPS22917EVMThe TPS22917EVM is an evaluation and demonstration board, used to easily demonstrate the capabilities of several Texas Instruments’ (TI) devices, such as the TPS22917 and TPS22919. The boards are designed to allow users to easily evaluate the features, functions and performance of these TI devices without having to design a custom circuit board. The TPS22917EVM provides an easy-to-use platform to quickly build and debug a system that utilizes the TPS22917/19 Digital Load Switches. The EVM can be powered up with 5V and 3.3V or 1.8V DC for the load switch. It provides several different ways to measure the load switch performance and monitor the load switch status, such as toggling the enable/disable, reading the load switch status, current measurement, and voltage measurement. The TPS22917EVMs have two primary applications in the research fields. One is for power-up/down sequencing, which means the power-up and/or power-down sequencing can be quickly implemented and tested using the provided control circuitry. And the other is drive/sense control. This configuration allows for current, voltage, and faulty condition monitoring and control.In terms of working principle, a Digital Load Switch is an electronic switch device used to control current flows and power sequencing ICs. This type of device allows an integrated circuit to function as a switch, which can efficiently control the amount of power supplied from one source to another. The TPS22917EVM implements a digital load switch, providing a simple and efficient way to switch power supply paths with good power management performance and long life. The EVM can be used in circuit boards for various industrial, medical, automotive, and consumer electronics applications where current or voltage need to be switched accurately.The TPS22917EVM’s enable/disabling and fault detection features can be utilized to implement power-up/down sequencing for a variety of circuits and equipment, such as microprocessors, memory, I/O, and peripherals. When enable signal is asserted, the TPS22917EVM will switch the power supply path to the desired load path and when the enable signal is deasserted, the TPS22917EVM will switch the power supply path back. This provides users more flexibility in controlling power sequencing and preventing any potential damage caused by unexpected power faults.In addition, the TPS22917EVM provides a reliable and simple drive/sense control feature with precise power control and long-term reliability. The load switches on the EVM may be used to drive/sense control the load beyond their rated values, which can help maintain the voltage or current to the desired levels. The drive/sense control feature can help to reduce power consumption as well as detecting any potential faults that could occur during operation.In summary, the TPS22917EVM is a reliable and efficient evaluation board that can help make the task of powering up/down sequencing for any device easier and faster. With its drive/sense control feature, it can provide users with reliable and precise power control to their desired levels and monitor any potential faults that could occur during operation. The TPS22917EVM is an ideal board to evaluate the features, functions and performance of TI’s TPS22917 and TPS22919.
