Supervisors

TPS3808G09DBVRG4 Description

The TPS3808G09DBVRG4 is a precision voltage supervisor IC from Texas Instruments, designed to monitor single-voltage power supplies in electronic systems. Housed in a compact SOT23-6 package, this obsolete but reliable component ensures system integrity by generating a reset signal when the supply voltage falls below a fixed threshold of 0.84V. Its open-drain output allows flexible integration with various logic levels, while its adjustable/selectable reset timeout feature enables customization for specific system requirements. Compliant with ROHS3 and REACH standards, it is suitable for environmentally conscious designs.

TPS3808G09DBVRG4 Features

• Precision Monitoring: Fixed threshold voltage of 0.84V ensures accurate detection of power supply anomalies.
• Flexible Output: Open-drain or open-collector output supports multiple logic interfaces.
• Adjustable Reset Timeout: Configurable delay allows tailored system recovery timing.
• Compact & Robust: SOT23-6 surface-mount package saves board space and suits high-density designs.
• Low Power Consumption: Ideal for battery-operated and power-sensitive applications.
• Compliance: Meets ROHS3 and REACH environmental standards.

TPS3808G09DBVRG4 Applications

• Embedded Systems: Ensures reliable microcontroller reset during power fluctuations.
• Battery-Powered Devices: Monitors low-voltage conditions in portable electronics.
• Industrial Controls: Provides fail-safe supervision in automation and sensor systems.
• Consumer Electronics: Protects critical circuits in smart home devices and wearables.
• Automotive Electronics: Enhances reliability in infotainment and telematics systems (though not AEC-Q qualified).

Conclusion of TPS3808G09DBVRG4

The TPS3808G09DBVRG4 is a specialized voltage supervisor offering precision, flexibility, and compactness for power monitoring applications. While marked obsolete, its adjustable reset timeout and low-voltage threshold make it a viable choice for legacy designs or cost-sensitive projects requiring reliable power supervision. Engineers should evaluate alternative TI supervisors for new designs but can leverage this IC’s proven performance in existing systems.
