TPS22913CYZVR

TPS22913CYZVR is a power distribution switch, load driver, and bidirectional battery switch, which is a member of TI\'s TPS22900 family of integrated devices. It has been designed to offer a high degree of efficiency and simplify the design of power management and control applications. It\'s an excellent choice for automotive, consumer and portable applications.

The TPS22913CYZVR integrates a power distribution switch, two MOSFETs, and a reverse voltage protection circuit into a single package. The integrated MOSFETs support a load current of 4.5A, maximizing efficiency and reducing system power dissipation. The reverse voltage protection circuit allows the switch to control power to the system from battery sources, ensuring the device operates safely and reliably from dual battery supplies. The integrated reverse polarity protection prevents transients from flowing back into the system, reducing the risk of damage to the system.

The device includes an enable pin that allows the switch to be enabled or disabled. The enable pin also features several features, including a low-current enable mode, an analog enable pin, and a time-delay enable mode. Low-current enable mode allows current draw to be reduced when the switch needs to be enabled, minimizing power dissipation. The analog enable pin allows the switch to be enabled at a specific voltage, allowing the designer to customize how the switch is enabled depending on the application. The time-delay enable feature allows the switch to be enabled at a preset delay, allowing the system to power up in a controlled manner.

The device also includes over-current and over-temperature protection, which provide additional protection against potential damage or system instability. The over-current protection sets a maximum limit on the current that can be drawn through the switch, allowing the device to be operated safely. The over-temperature protection shuts off the switch when it reaches a predetermined temperature, offering additional system safety.

Although the TPS22913CYZVR offers Protection from reverse polarity, over current, and over temperature, it doesn\'t offer protection from short-circuit or ESD. Designers need to ensure that any external components connected to the switch are appropriately protected. The device should also be connected to a good ground to ensure the system is properly protected.

The TPS22913CYZVR is ideal for applications in the automotive industry, consumer electronics, and portable applications. It offers an efficient, low-power solution to manage power control and distribution. With its reverse polarity protection, current limiting, temperature protection, and control options, the TPS22913CYZVR offers an excellent option for managing power in these applications.
