TLV809EA17DBZR

Supervisors Overview

The TLV809EA17DBZR is a low-power voltage supervisor from the TLV809E series, manufactured by Texas Instruments. It operates within a supply voltage range of 1.7 V to 6 V and features a fixed threshold voltage of 1.7 V with 0.5% accuracy. The device provides an active-low, push-pull output and includes a manual reset function. It has a reset delay time of 200 ms and no watchdog timer. The component is housed in an SOT-23 package and supports surface-mount installation. It functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Includes a manual reset input for external control of the reset state
• Features high precision threshold detection with 0.5% accuracy
• Provides an active-low push-pull output driver

Supervisors Applications

• Portable battery-powered equipment requiring low quiescent current
• Microcontroller power supply monitoring systems
• Embedded systems needing reliable brown-out protection

Supervisors Procurement Notes

Verify the specific suffix DBZR corresponds to the SOT-23 package and reel packaging configuration. Confirm the EA17 designation matches the required 1.7 V threshold and manual reset functionality. Ensure compatibility with the target operating temperature range of -40°C to +125°C. Cross-reference the manufacturer part number against official datasheets to validate pinout and electrical specifications before integration.

Supervisors Selection Notes

Select this component when a precise 1.7 V supervision level is required alongside manual reset capability. The TLV809E series offers superior accuracy compared to standard variants. Consider the SOT-23 footprint for space-constrained designs. Verify that the 200 ms reset delay aligns with system startup timing requirements. Evaluate the low power consumption benefits for battery-operated applications.

Supervisors Part Context

This part belongs to the TLV809E family of voltage supervisors, distinguished by enhanced accuracy and specific feature sets like manual reset. It complements other TLV809 variants such as the TLV809EF30DBZR or TLV809EA29DBZR, which offer different thresholds or lack manual reset inputs. The family targets general-purpose power management needs in consumer and industrial electronics.

Supervisors Replacement Considerations

Direct substitutes include TLV809EA29DBZR for similar features at a different threshold. For non-manual reset options, consider TLV809EF30DBZR. Verify package compatibility and electrical parameter alignment when substituting.
