TPS3779DDRYT

Supervisors Overview

The TPS3779DDRYT is a low-power dual voltage detector manufactured by Texas Instruments, housed in a compact SON-6 surface-mount package. It features two adjustable sense inputs with hysteresis to suppress noise and ensure stable output operation. The device provides active low push-pull outputs that transition states based on whether the sensed voltages cross their respective thresholds. It operates within a supply voltage range of 1.5 V to 6.5 V and maintains a typical quiescent current of 2 µA. The component supports manual reset functionality and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with adjustable threshold configuration via external resistors
• Ultra-low static current consumption for extended battery life in portable applications
• Integrated hysteresis on sense inputs to prevent erroneous triggering from signal noise
• Active low push-pull output drivers for direct interface with digital logic systems

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing precise voltage supervision
• General-purpose system monitoring in industrial environments

Supervisors Procurement Notes

Verify the specific suffix DDRYT corresponds to the SON-6 package and reel/cut-tape availability when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accounts for the adjustable threshold requirements using appropriate external resistor networks. Validate thermal performance within the specified operating temperature range during final assembly planning.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in space-constrained designs. The adjustable thresholds offer flexibility compared to fixed-voltage detectors. Consider the SON-6 footprint against available board real estate. Evaluate the 2 µA quiescent current benefit against total system power budgets. Verify compatibility with the target logic levels provided by the push-pull outputs.

Supervisors Part Context

This part belongs to the TPS3779 series of supervisory circuits designed for low-power applications. It complements other Texas Instruments PMIC solutions by providing dedicated voltage detection capabilities. The series emphasizes small form factors and high accuracy for modern embedded systems. It serves as a critical component for ensuring system stability during power-up and power-down sequences.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the same family if package availability is constrained. Verify that substitute parts maintain the dual-input architecture and adjustable threshold capability. Ensure any replacement supports the required 6.5 V maximum supply voltage and similar quiescent current specifications.
