TPS3809I50 Description

Short technical summary and product information.

The Texas Instruments TPS3809I50 is a versatile 3-pin supply voltage supervisor IC. It provides essential circuit initialization and timing supervision for processor-based systems, including DSPs, microcontrollers, and microprocessors.

 

This device operates across a supply voltage range of 2.5 V to 5 V, with a typical supply current of just 9 μA. It features a precision supply voltage monitor that asserts RESET when VDD drops below a threshold and maintains it until the supply recovers. The internal timer provides a typical delay of 200 ms after the supply voltage rises above the threshold.

 

The TPS3809I50 is available in a compact 3-pin SOT-23 package, suitable for surface mount applications. It is characterized for operation over a wide temperature range of -40°C to +85°C, making it suitable for various industrial and portable equipment applications.

 

Key applications include wireless communication systems, battery-powered devices, programmable controls, intelligent instruments, industrial equipment, notebook/desktop computers, and automotive systems.
