TPS3899DL41DSER

Supervisors Overview

The TPS3899DL41DSER is a nanopower voltage supervisor manufactured by Texas Instruments, designed for monitoring single-channel power rails. It operates within a supply voltage range of 0.8 V to 6 V and features a fixed threshold voltage of 4.1 V. The device provides an active-low, open-drain reset output with a manual reset input capability. It incorporates programmable sense inputs and adjustable reset delay timing to accommodate various system requirements. The component is housed in a compact WSON-6 package (1.5x1.5 mm) suitable for surface-mount applications. It supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Nanopower consumption architecture optimized for battery-operated systems
• Programmable sense inputs allow flexible voltage monitoring configurations
• Adjustable reset delay timing enables precise synchronization with system startup sequences
• Manual reset input provides direct control over the reset state

Supervisors Applications

• Portable electronic devices requiring low quiescent current
• Battery-powered embedded systems needing reliable power supervision
• Industrial equipment operating in extreme temperature environments
• Automotive electronics requiring robust voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix DSER indicates reel packaging when ordering. Confirm the threshold voltage matches the design requirement of 4.1 V. Ensure the WSON-6 footprint aligns with the PCB layout. Check RoHS compliance status if required by project specifications. Validate the operating temperature range against environmental conditions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with programmable features is needed. Consider the 4.1 V threshold for systems operating near this voltage level. Evaluate the need for adjustable reset delays versus fixed timing alternatives. Compare quiescent current requirements against other supervisors in the TPS3899 family. Ensure the open-drain output compatibility with downstream logic levels.

Supervisors Part Context

This part belongs to the TPS3899 series of nanopower supervisors from Texas Instruments. The series offers various threshold voltages and package options to suit different application needs. The DL41 variant specifically sets the trip point at 4.1 V. The EVM (Evaluation Module) is available for testing performance characteristics. The family includes variants with different output types and delay settings.

Supervisors Replacement Considerations

Other TPS3899 variants with different threshold voltages may serve as functional substitutes if the voltage level differs. Devices from the TPS38xx family with similar packages can be considered for pin-compatible replacements. Verify that alternative parts support the same manual reset functionality and output configuration.
