LM393LVPWR

Overview

The LM393LVPWR is a dual low-voltage comparator from Texas Instruments, housed in an 8-pin TSSOP package. It operates within a supply voltage range of 1.65 V to 5.5 V and features rail-to-rail input capability with failsafe functionality. Key electrical parameters include a typical propagation delay of 600 ns, a maximum quiescent current of 25 uA per channel, and a typical input offset voltage of 400 μV. The device supports open-drain outputs and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail input stage with integrated failsafe protection
• Low power consumption suitable for battery-operated systems
• Wide single-supply voltage operation range

Applications

• Battery-powered monitoring circuits
• Threshold detection in low-voltage systems
• Temperature sensing interfaces

Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-8 package and reel/cut-tape availability. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 1.65 V minimum operating voltage.

Selection Notes

Select this component when rail-to-rail input performance and ultra-low quiescent current are critical. It serves as a low-voltage alternative to standard comparators requiring higher supply voltages. Consider the 600 ns propagation delay for timing-sensitive applications.

Part Context

This part belongs to the LM393LV family of low-voltage comparators. It offers enhanced precision compared to standard LM393 variants, featuring significantly lower input offset voltage and improved common-mode rejection. The device maintains compatibility with standard logic levels while optimizing power efficiency.

Replacement Considerations

LMV393IPWR: Higher speed but limited to 2.7 V minimum supply. LM393DR: Standard voltage version requiring higher supply voltage.
