TPS3306 Description

Short technical summary and product information.

The TPS3306 family from Texas Instruments offers dual supervisory circuits with power-fail and watchdog timer capabilities, specifically designed for initializing circuits that require two supply voltages, commonly found in DSP and processor-based systems.

This series is engineered for monitoring two independent supply voltages, with variants supporting configurations such as 3.3V/1.5V, 3.3V/1.8V, 3.3V/2V, 3.3V/2.5V, and 3.3V/5V. Key electrical features include a wide supply voltage range of 7V to 6V, a low typical supply current of 15 μA, and a defined RESET output from VDD ≥ 1.1V. The device incorporates a watchdog timer with a 0.8-second timeout and a power-on reset generator with an integrated 100 ms delay.

It provides open-drain reset and power-fail outputs. The operating temperature range spans from -40°C to +85°C, making it suitable for various environmental conditions. The TPS3306 is available in MSOP-8 and SO-8 packages, supporting surface mount applications.

Applications for the TPS3306 include multivoltage DSPs and processors, portable battery-powered equipment, embedded control systems, intelligent instruments, and automotive systems. Its robust design ensures reliable system initialization and monitoring.
