TPS3808G50DBVR Low-Quiescent-Current Voltage Supervisor
The TPS3808G50DBVR is a high-precision, low-power microprocessor supervisory circuit manufactured by Texas Instruments (TI). Designed for monitoring 5V power rails, it features a fixed 4.65V threshold voltage with 0.5% typical accuracy, ensuring reliable voltage detection. Housed in a compact SOT-23-6 surface-mount package, it operates from 1.7V to 6.5V supply voltage and covers an industrial temperature range of -40°C to +125°C. This device asserts an open-drain RESET signal when the monitored voltage drops below the threshold or when the manual reset (MR) pin is pulled low, providing robust system protection against undervoltage conditions.
TI voltage supervisor Key Features & Application Scenarios
This voltage supervisor integrates critical features including ultra-low quiescent current (2.4µA typical), programmable reset delay (1.25ms to 10s via external capacitor), manual reset input, and open-drain output. It offers fixed 5V threshold for standard power systems, high threshold accuracy, and wide operating temperature range, making it ideal for battery-powered and industrial applications. Primary applications include portable medical devices, IoT sensor nodes, industrial control systems (PLCs), automotive electronics (TPMS, ADAS), and consumer electronics (wearables, smart home devices), where it ensures stable system operation by preventing improper initialization or corruption due to power glitches.
