TPS3305-18DGN Description

Short technical summary and product information.

The Texas Instruments TPS3305-18DGN 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 an external capacitor. The integrated watchdog timer helps retrigger the RESET output.

 

This supervisor monitors two supply voltages, with typical threshold voltages available at 1.68V and 2.93V. It offers reset accuracy within 3% and operates with a low quiescent current of 0.04mA. The output driver type supports active-high, active-low, and push-pull configurations. The device has a supply voltage range of 2.7V to 6V and a defined RESET output from VDD ≥ 1.1V.

 

The TPS3305-18DGN is available in an 8-HVSSOP package and operates within a temperature range of -40°C to +85°C. It is suitable for applications such as processor supply monitoring, industrial equipment, automotive systems, portable/battery-powered equipment, wireless communication systems, and notebook/desktop computers.
