The Texas Instruments TPS3305-33DR is a dual-processor voltage supervisor featuring a watchdog timer and a power-on reset generator with a fixed delay time of 200ms. This device is designed to monitor two supply voltages, with typical threshold options including 1.68V, 2.25V, 2.93V, and 4.55V. It offers active-high and active-low reset outputs with a push-pull driver type.
The TPS3305-33DR operates over an industrial temperature range of -40°C to 85°C and requires a supply voltage between 2.7V and 6V. The reset output is defined from a VDD of 1.68V. Its maximum supply current is a low 40µA, making it suitable for portable and battery-powered applications. The watchdog timer function re-triggers the RESET output when SENSEn is greater than or equal to V IT+.
This supervisor IC is available in an 8-SOIC package, measuring 4.9 mm × 6 mm. It is commonly used in applications such as processor supply monitoring, industrial equipment, automotive systems, wireless communication systems, and notebook/desktop computers. The device includes features like manual reset capability and a temperature-compensated voltage reference.
