TPS3306-15DR Description

Short technical summary and product information.

The Texas Instruments TPS3306-15DR is a dual-processor supervisory circuit designed for DSP and processor-based systems. It provides critical monitoring functions including voltage supervision for power-fail or low-battery warnings, and a watchdog timer with a 0.8-second timeout.

 

The device features a power-on reset generator with an integrated 100 ms delay time and an open-drain reset and power-fail output. It monitors up to two supply voltages with selectable threshold options and offers a reset threshold accuracy of 2.4% or 3.2%. The operating temperature range is -40°C to +85°C.

 

This supervisor IC is suitable for applications such as multivoltage DSPs and processors, portable battery-powered equipment, embedded control systems, intelligent instruments, and automotive systems. It is supplied in an 8-SOIC package, supporting surface mount installation.

 

Key electrical characteristics include a typical supply current of 15 µA and a supply voltage range from 1.1V to 6V. The reset output is defined from VDD ≥ 1.1V.
