The Texas Instruments TPS3305-33DGN 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 integrated watchdog timer retriggers the RESET output, ensuring system stability.
This supervisor monitors two supply voltages, with typical threshold options including 1.68V, 2.25V, 2.93V, and 4.55V. It offers a reset threshold accuracy of 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 TPS3305-33DGN operates within a supply voltage range of 2.7V to 6V and provides a defined RESET output from 1.1V. It is available in an 8-HVSSOP package and operates across a temperature range of -40°C to 85°C. Key features include complimentary output, manual reset capability, separate VDD & sense, timeout watchdog, and undervoltage monitoring.
Applications for this device include processor supply monitoring, industrial equipment, automotive systems, portable/battery-powered devices, wireless communication systems, and notebook/desktop computers.
