TPS3305-33DGNR Description

Short technical summary and product information.

The Texas Instruments TPS3305-33DGNR is an integrated circuit designed for dual-processor supervision. It features a watchdog timer to ensure system responsiveness and provides a power-on reset generator with a fixed delay time of 200ms, eliminating the need for external capacitors.

 

This supervisor monitors two supply voltages, with typical threshold options including 1.68V, 2.25V, 2.93V, and 4.55V. It offers features such as complimentary outputs, manual reset capability, separate VDD and sense pins, and an undervoltage monitor. The reset threshold accuracy is within 3%, and the typical quiescent current is 0.04mA.

 

The TPS3305-33DGNR operates over a supply voltage range of 2.7V to 6V and has a defined RESET output from VDD >= 1.1V. It is available in an 8-MSOP package and operates within a temperature range of -40°C to +85°C.

 

Applications for this device include processor supply monitoring, industrial equipment, automotive systems, portable and battery-powered devices, wireless communication systems, and notebook/desktop computers.
