The TPS25740ARGET is an ultra-low quiescent current load switch ideal for using in system-on-chip (SoC) and system-in-package (SiP) solutions. It has an integrated low-resistance MOSFET and is intended for use in space-limited and low-power applications. It is a very convenient load switch that is suitable for multiple voltage domains and can efficiently manage multiple power rail connections.

Uses

The TPS25740ARGET is mainly used to connect and disconnect components in electronic circuits. It can switch loads that require high-current and high-voltage range and control the power supply in low-power and low-voltage applications. It can also be used to improve system start-up behavior by ensuring that critical components are powered when system initializations occur. It can also be used to protect components from the power glitches caused by board layout issues, saving time and effort from re-spins.

Application Fields

The TPS25740ARGET is mainly used in mobile and consumer devices such as smartphones, tablets, wearables, and laptops. It is also used in IoT devices and applications such as smart meters, security systems, and intelligent lighting. Furthermore, the TPS25740ARGET can also be used in automotive, industrial automation, energy storage systems, and power supply systems.

Working Principle

The TPS25740ARGET operates on an input voltage of 1.5V to 5.5V and is designed to switch up to 5.5V when the gate voltage exceeds the source voltage. It can also be used in systems with a dual voltage domain such as 1.5V and 5V. When the input voltage is present, the load switch will open, allowing current to flow and connecting the load to the power rail. When the input voltage is removed, it will close the switch and disconnect the load from the power supply.

The TPS25740ARGET also offers power good signal to indicate when the power is reliable for the system. It is capable of detecting undervoltage and voltage trans fluctuations, making it suitable for protecting system against sudden changes in power supply.

Conclusion

The TPS25740ARGET is an efficient and reliable load switch for managing multiple power rail connections. It can easily be used in low-voltage applications to protect components from power glitches, improve system starts-up behavior and switch loads requiring high-current and high-voltage ranges. It is mainly used in mobile and consumer devices, IoT applications, automotive, industrial automation and energy storage systems.
