The TPS3809J25DBVR is a high-precision, programmable voltage supervisor from Texas Instruments, designed to monitor power supplies in microprocessor and digital systems. It provides a crucial safeguard for systems that require a stable and reliable operation by triggering a reset signal whenever the VCC supply voltage drops below a predetermined threshold.

Key Features

• Voltage Threshold: The device features a fixed-sense threshold voltage of 2.5V, which is ideal for 2.5V power supply applications.
• Low Power Consumption: With a very low quiescent current of 9 μA, the TPS3809J25DBVR is optimized for battery-powered and low-power applications.
• Reset Time Delay: It includes a programmable time delay for the reset, allowing designers to set the duration of the reset signal as per system requirements.
• High Accuracy: The device offers high threshold accuracy of ±2%, ensuring reliable monitoring and reset activation.
• Manual Reset: A manual reset input is provided, allowing for a system reset to be initiated by external events or user interaction.
• Temperature Range: The operational temperature range of -40°C to +85°C allows for deployment in a wide range of environmental conditions.
• Small Form Factor: Packaged in a compact SOT-23-6 package, the TPS3809J25DBVR is suitable for space-constrained applications.
