TPS3306-15DGKR Description

Short technical summary and product information.

The Texas Instruments TPS3306-15DGKR is a dual-processor supervisory circuit designed for DSP and processor-based systems. It provides voltage monitoring for power-fail or low-battery warnings, a watchdog timer with a 0.8-second timeout, and a power-on reset generator with an integrated 100 ms delay.

 

This supervisor IC monitors up to three supplies with selectable threshold voltages including 1.4V, 1.68V, 1.85V, 2.25V, 2.93V, and 4.55V. It offers an active-low, open-drain reset output and a power-fail output. The device operates over a temperature range of -40°C to 85°C and has a low supply current of 15 µA typical.

 

Packaged in an 8-VSSOP, the TPS3306-15DGKR is suitable for surface mounting. Its features make it ideal for applications such as multivoltage DSPs and processors, portable battery-powered equipment, embedded control systems, intelligent instruments, and automotive systems.
