The TPS3306-25DGKR from Texas Instruments is a dual-processor supervisory circuit designed for initializing systems that require monitoring of two independent supply voltages. This device is suitable for DSP and processor-based systems, offering features such as a watchdog timer with a 0.8-second timeout and a power-on reset generator with a 100ms delay.
Key electrical characteristics include monitoring two voltage levels (2.25V and 2.93V) with an active-low reset output defined from VDD >= 1.1V. The supervisor operates within a supply voltage range of 1.1V to 7V and consumes a typical supply current of 15µA. The output configuration is open-drain or open-collector, providing flexibility in system design.
Packaged in an 8-VSSOP, the TPS3306-25DGKR is designed for surface mounting. It operates across a wide temperature range of -40°C to 85°C, making it suitable for various environmental conditions. Applications include multivoltage DSPs and processors, portable battery-powered equipment, embedded control systems, intelligent instruments, and automotive systems.
