The Texas Instruments TPS3305-25DGNR is a dual-processor voltage supervisor designed for DSP- and processor-based systems. It monitors two supply voltages and provides a reset output with a fixed delay time of 200ms, eliminating the need for an external capacitor. The device includes a watchdog timer that re-triggers the reset output under specific conditions.
Key electrical specifications include a supply voltage range of 2.7V to 6V, with the reset output defined from 1.1V. The typical quiescent current is 0.04mA, and the maximum supply current is 40µA. It offers multiple threshold voltage options (1.68V, 2.25V, 2.93V, 4.55V) with a reset threshold accuracy of 3% and a watchdog timer interval of 1.6 seconds.
The TPS3305-25DGNR supports active-high and active-low reset outputs with push-pull drivers. It operates across a temperature range of -40°C to 85°C. The component is available in 8-HVSSOP and 8-MSOP packages, both suitable for surface mounting.
Applications for this supervisor include processor supply monitoring, industrial equipment, automotive systems, portable and battery-powered devices, wireless communication systems, and notebook/desktop computers.
