Functional Features

• Precision monitoring of supply voltage
• Programmable reset threshold voltage
• Adjustable reset timeout period
• Manual reset capability
• Open-drain reset output

Working Principles

The TPS3808G50DBVR operates by continuously monitoring the supply voltage. When the voltage falls below the programmed threshold, the reset output is asserted, indicating a power-on reset condition. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The TPS3808G50DBVR is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some typical application fields include: - Microcontroller-based systems - Industrial control systems - Automotive electronics - Battery-powered devices - Home automation systems
