The TPS2491DGSR is a high-performance power manager that has been engineered to help simplify power sequencing requirements for any system that requires multiple voltage sources to be supplied in a specific order. Designed by Texas Instruments, this device is a must-have for any design engineer looking to create stable, reliable power supplies that require precision timing and control. In this product introduction, we will explore the key features and benefits of the TPS2491DGSR and how it can add value to your products.

One of the primary benefits of the TPS2491DGSR is its ability to simplify the sequencing of multiple voltage sources. This is a critical requirement for many power systems and can often be challenging to implement, particularly when using discrete components. However, the TPS2491DGSR eliminates this complexity by providing a seamless, integrated solution that can handle up to four power rails, including the main system power supply, both primary and secondary voltage rails, and an auxiliary voltage supply.

Another key benefit of the TPS2491DGSR is its flexibility. With this device, you can easily configure your power sequencing requirements using a simple, intuitive interface. This allows you to specify your desired power-up and power-down sequences, including any time delays or other timing requirements. You can also program the device to respond to specific system events, such as a reset or a fault condition, which can help improve system stability and reliability.

The TPS2491DGSR also offers a high degree of precision and accuracy. With a built-in reference voltage generator and current sensing circuitry, the device can accurately monitor and regulate voltage and current levels in real-time. This results in a more stable and reliable power supply, which can help improve system performance and reduce the risk of component failures.

Another feature that sets the TPS2491DGSR apart from other power management solutions is its high level of integration. The device includes a host of built-in safety and protection features, including overcurrent and overvoltage protection, as well as thermal shutdown and undervoltage lockout. These safety features help protect your system from damage and ensure that it operates within safe operating limits.

The TPS2491DGSR is also highly efficient, thanks to its low standby current and low power consumption in active mode. This results in a power management solution that uses less energy, generates less heat, and extends battery life - a critical requirement for many portable and wireless devices.

In terms of packaging and installation, the TPS2491DGSR is available in a compact, space-saving package that can be easily integrated into any system design. The device is also straightforward to install, with a minimal number of external components required for operation. This helps reduce design complexity, shorten time-to-market, and decrease overall system cost.

In summary, if you're looking for a reliable, flexible, and highly-integrated power management solution that can handle complex sequencing requirements, the TPS2491DGSR is an excellent choice. With its high degree of precision, safety features, and low power consumption, this device can help improve system performance, reduce component failures, and extend battery life. Plus, with its compact form factor and ease of installation, it's a perfect fit for any system design. If you're interested in learning more about the TPS2491DGSR or need help integrating it into your system, please don't hesitate to contact us. We're here to help!

Description

The TPS249x are easy-to-use, positive high voltage,10-pin Hot Swap Power Manager devices that safely

drive an external N-channel MOSFET switch. The power limit and current limit (both are adjustable and

independent of each other) ensure that the external MOSFET operates inside a selected safe operating

area (SOA) under the harshest operating conditions.

Applications include inrush current limiting, electronic circuit breaker protection, controlled load turn-on,

interfacing to down-stream DC-to-DC converters, and power feed protection. These devices are available in a small, space-saving 10-pin VSSOP package and significantly reduce the number of external devices,

saving precious board space. The TPS249x is supported by application notes, an evaluation module, and a design tool.
