TPS3106K33DBVR

Supervisors Overview

The TPS3106K33DBVR is a voltage supervisory circuit from Texas Instruments designed for monitoring supply voltages. It operates within a supply range of 400 mV to 3.3 V and features a fixed threshold voltage of 2.941 V with an accuracy of 0.75%. The device provides an active-low, open-drain reset output with a typical delay time of 130 ms. It supports manual reset functionality and consumes a maximum operating supply current of 32 uA. The component is housed in a SOT-23-6 package and is rated for operation between -55°C and +125°C.

Supervisors Feature Summary

• Ultra-low supply current consumption suitable for battery-powered applications
• Fixed threshold voltage detection with high accuracy
• Manual reset capability for system control
• Compact surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring low power supervision
• Battery-operated systems needing voltage monitoring
• Embedded controllers requiring reliable reset signals
• Industrial equipment operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix 'DBVR' indicates the tape-and-reel packaging configuration. Confirm that the K33 designation corresponds to the required 2.941 V threshold for your design. Ensure compatibility with the SOT-23-6 footprint during PCB layout. Check RoHS compliance status if restricted substances are a constraint for your project.

Supervisors Selection Notes

Select this part when a fixed 3.3 V rail requires supervision with minimal quiescent current. The 0.75% accuracy ensures precise detection compared to standard 5% variants. Consider the SOT-23-6 package size constraints and the need for manual reset input. Verify that the 130 ms delay meets the microcontroller startup timing requirements.

Supervisors Part Context

This component belongs to the TPS3106 family of ultra-low supply current voltage supervisors. It shares the same core architecture as other TPS3106 variants but differs in threshold voltage and packaging options. The series is designed for applications where power efficiency and space savings are critical priorities.

Supervisors Replacement Considerations

Check for TPS3106K33DBVT as a tray alternative. Verify TPS3106K33MDBVREP for military-grade specifications. Ensure any substitute maintains the 2.941 V threshold and SOT-23-6 package compatibility.
