The TPS2090DR, manufactured by Texas Instruments, is a state-of-the-art power distribution switch designed for applications requiring multiple power switches in a single package. This integrated circuit (IC) is part of the TPS209x family and is specifically crafted to enhance the functionality and safety of systems by managing power distribution efficiently.
This robust device comes in an 8-pin SOIC package, offering a compact solution for space-constrained applications. It features dual-channel, 0.5A current-limited power switches, which are ideal for USB and other hot-swap applications. The TPS2090DR is designed to operate over a wide input voltage range of 2.7V to 5.5V, making it versatile for various system designs.
Key features of the TPS2090DR include built-in thermal overload protection, which prevents damage to the IC from excessive power dissipation. It also has under-voltage lockout to ensure the power switch remains off when the input voltage is below a certain threshold, thereby safeguarding the connected devices. Additionally, the TPS2090DR boasts over-current and short-circuit protection, which limits the output current to safe levels during fault conditions.
The device's fault status is reported back to the system via an open-drain fault signal, allowing for intelligent system responses to power issues. Moreover, the TPS2090DR is characterized for operation from -40°C to 85°C, ensuring reliable performance even in extreme conditions. The power switch also supports a quick output discharge that enables swift turn-off of downstream capacitors when the switch is disabled.
The TPS2090DR is an excellent choice for designers looking for a reliable and efficient solution to manage power distribution in their systems. Its advanced protection features and compact form factor make it a valuable component for a wide range of applications, including USB hubs, peripheral ports, and hot-swap supplies.
