TPS3305-25DR Description

Short technical summary and product information.

The Texas Instruments TPS3305-25DR 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 device includes a watchdog timer that retriggers the RESET output when SENSEn is greater than or equal to VIT+. It offers temperature-compensated voltage references and operates with a maximum supply current of 40µA.

 

The TPS3305-25DR monitors two supply voltages, with typical threshold voltages available at 1.68V, 2.25V, 2.93V, and 4.55V. The reset threshold accuracy is 3%. The output driver type and reset output can be active-high, active-low, or push-pull. The device has a reset timeout of 140ms minimum and a watchdog timer interval of 1.6 seconds.

 

This supervisor operates within a supply voltage range of 2.7V to 6V, with a defined RESET output from VDD >= 1.1V. It is available in an 8-SOIC package measuring 4.9 mm x 6 mm and an 8-HVSSOP package measuring 3 mm x 4.9 mm. The operating temperature range is -40°C to +85°C.

 

Applications for the TPS3305-25DR include processor supply monitoring, industrial equipment, automotive systems, portable/battery-powered equipment, wireless communication systems, and notebook/desktop computers.
