TPS3305-18DR Description

Short technical summary and product information.

The TPS3305-18DR from Texas Instruments is a micropower dual-processor voltage supervisor designed for circuit initialization in DSP and processor-based systems. It monitors two supply voltages, essential for core and I/O requirements.

 

Key electrical specifications include a wide supply voltage range of 2.7V to 6V and a maximum supply current of 40µA. The device features a power-on reset generator with a fixed delay time and a watchdog timer that re-triggers the RESET output. The reset is asserted when the voltage at either SENSEn pin falls below its threshold voltage.

 

This supervisor operates within a temperature range of -40°C to 85°C. It is available in an 8-SOIC package, suitable for surface mount applications. The TPS3305 family is well-suited for applications such as processor supply monitoring, industrial equipment, automotive systems, and portable electronics.
