TPS2400DBVT

The Texas Instruments TPS2400DBVT is an overvoltage protection controller designed to isolate sensitive electronics from destructive voltage spikes and surges. It is specifically engineered to prevent large voltage transients, such as those found in automotive environments, from damaging connected circuitry. When potentially damaging voltage levels are detected, the TPS2400 disconnects the supply from the load before any damage can occur.

Key electrical features include up to 100V of overvoltage protection, a 6.9V overvoltage shutdown threshold, and a 3.0V undervoltage shutdown threshold. The overvoltage turn-off time is less than 1.0 µs, ensuring rapid response. It operates with a static supply current of 1mA maximum and supports an operating voltage range of 3.1V to 6.8V.

This device is housed in a compact 5-pin SOT-23 package and is suitable for surface mount applications. The operating temperature range is -40°C to 85°C. It also provides 2.5kV of Human-Body-Model and 500V CDM electrostatic discharge protection, making it robust for various applications.

Applications for the TPS2400 include cellular phones, PDAs, portable PCs, media players, digital cameras, and GPS devices, where robust power protection is critical.
