TI TPS2400DBVR 5.5V Overvoltage Protection Controller With 100V Input Transient Protection

Shenzhen Mingjiada Electronics Co., Ltd., a globally renowned distributor of electronic components, stocks the TPS2400DBVR 5.5V overvoltage protection controller, providing reliable voltage protection solutions for diverse electronic systems.

【Product Overview Of TPS2400DBVR】

The TPS2400DBVR is a controller chip specifically designed for power supply protection. When paired with an external N-channel MOSFET, it effectively isolates sensitive electronic components from destructive voltage spikes and surges.

The TPS2400DBVR offers 100V input transient protection, specifically engineered to prevent damage to sensitive circuits from high-voltage transients associated with automotive environments, such as load dumping.

Upon detecting potentially destructive voltage levels, the TPS2400DBVR rapidly disconnects the power supply from the load before any damage occurs, exhibiting extremely short response times.

Its overvoltage shutdown time is less than 1 microsecond, ensuring exceptionally rapid protection response. The TPS2400DBVR utilises a compact SOT-23-5 package, making it suitable for space-constrained applications.

【Core Features Of TPS2400DBVR】

Superior protection capability: The TPS2400DBVR supports overvoltage protection up to 100V, with an overvoltage shutdown time of less than 1µs, enabling rapid response to voltage anomalies.

Precise voltage monitoring: A 6.9V overvoltage shutdown threshold and 3V undervoltage shutdown threshold ensure the power supply operates within safe limits.

Efficient Internal Design: Integrates a charge pump, comparator, and control logic internally, with a maximum static supply current of just 1mA, contributing to reduced system power consumption.

Wide Operating Conditions: Operates within a supply voltage range of 3.1V to 6.8V and a temperature range of -40°C to 85°C, enabling adaptation to demanding environments.

Compact packaging: The TPS2400DBVR utilises an SOT-23-5 package, saving PCB space and making it suitable for high-density designs.

【Technical Specifications Of TPS2400DBVR】

The TPS2400DBVR operates within a voltage range of 3.1V to 6.8V, featuring an overvoltage protection threshold of 6.9V and an undervoltage lockout threshold of 3.0V.

The TPS2400DBVR exhibits exceptionally low quiescent power consumption, with a maximum of just 1mA, contributing to reduced overall system power usage. The device can withstand continuous overvoltage events up to 100V, delivering robust protection capabilities.

Operating within an ambient temperature range of -40°C to 85°C, the TPS2400DBVR is suitable for diverse harsh-environment applications. It also offers robust electrostatic discharge (ESD) protection: 2.5kV human body model (HBM) and 500V conductive discharge model (CDM).

The TPS2400DBVR utilises a compact SOT-23-5 package, ideal for high-density PCB layouts. With a dissipation rating of 285mW, it delivers excellent power handling capability within its small footprint.

【Versatile Application Scope Of TPS2400DBVR】

The TPS2400DBVR serves diverse power supply scenarios. Within battery-powered portable devices, its low dropout voltage and ultra-low quiescent current contribute to extended battery life.

Automotive electronics represent a key application domain for this controller, providing power management protection against damage from events such as load dump.

Industrial control systems similarly benefit from the TPS2400DBVR's capabilities, as it delivers stable power protection within these systems. Such protection is also required in communications equipment to ensure power supply stability and reliability.

Specific product applications include: mobile phones, PDAs, portable computers, media players, digital cameras, and GPS devices.
