TPS3899DL22DSER

Supervisors Overview

The TPS3899DL22DSER is a nanopower voltage supervisor from Texas Instruments designed for monitoring single-input power rails. It operates within a supply voltage range of 0.8 V to 6 V and features a fixed threshold voltage of 2.2 V with 0.5% accuracy. The device provides an active low, open-drain output and includes manual reset functionality. It draws only 125 nA of quiescent current and offers a reset delay time of 40 µs. Operating temperatures span from -40°C to +125°C in a compact WSON-6 package.

Supervisors Feature Summary

• Ultra-low static current consumption for extended battery life
• High precision voltage threshold detection capability
• Integrated manual reset input for system control

Supervisors Applications

• Portable electronic devices requiring minimal standby power
• Battery-powered instrumentation systems
• Embedded controllers needing reliable power supervision

Supervisors Procurement Notes

Verify the specific suffix DSER indicates tape and reel packaging configuration. Confirm the DL22 designation corresponds to the 2.2 V threshold variant. Ensure compatibility with WSON-6 footprint requirements during procurement planning.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical alongside precise voltage monitoring. The fixed 2.2 V threshold suits applications requiring stable supervision without external programming components. Consider the WSON-6 package for space-constrained designs.

Supervisors Part Context

This part belongs to the TPS3899 series of nanopower supervisors. It shares the family's low-power architecture but differs in threshold voltage settings compared to other variants like TPS3899DL15 or TPS3899DL26.

Supervisors Replacement Considerations

TPS3899DL15DSER and TPS3899DL26DSER are pin-compatible alternatives within the same series offering different threshold voltages.
