TPS3305-18D Description

Short technical summary and product information.

The Texas Instruments TPS3305-18D is a dual-processor voltage supervisor designed for DSP- and processor-based systems. It features a power-on reset generator with a fixed delay time of 200ms, eliminating the need for external capacitors. The integrated watchdog timer helps retrigger the RESET output.

 

This supervisor monitors two supply voltages, with typical threshold voltages including 1.68V and 2.93V, and offers reset threshold accuracy of 3%. It operates over a wide temperature range of -40°C to 85°C. The device has a maximum supply current of 40µA and a defined RESET output from VDD ≥ 1.1V.

 

The TPS3305-18D is available in an 8-SOIC package, measuring 4.9mm x 6mm. Its features include complimentary outputs, manual reset capability, separate VDD and sense pins, and an undervoltage monitor. This makes it suitable for applications such as processor supply monitoring, industrial equipment, automotive systems, and portable electronics.
