Overview
The LMV7235M5X/NOPB is a single-channel, ultra-low power, low voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 5.5V and features rail-to-rail input capability. The device offers a typical propagation delay of 75ns at 5V while consuming only 65µA of supply current. It utilizes an open-drain output configuration, allowing for flexible interfacing through external pull-up resistors. Packaged in a compact 5-pin SOT-23 format, it supports operation across temperatures from -40°C to +85°C.
Feature Summary
- Rail-to-rail input stage enables detection of signals extending below ground and above the positive supply rail.
- Ultra-low power consumption design maintains minimal current draw during operation.
- Open-drain output architecture allows configurable logic levels via external pull-up components.
Applications
- Battery-powered portable electronics requiring extended operational life
- Low-voltage signal monitoring and threshold detection circuits
- Ground-referenced sensor interface applications
Procurement Notes
Verify the specific suffix 'M5X' indicates the SOT-23 package with tape-and-reel shipping configuration. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance status. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before procurement.
Selection Notes
Select this component when system constraints demand minimal quiescent current alongside rail-to-rail input flexibility. The open-drain output requires an external pull-up resistor, which must be sized according to the target logic family voltage levels. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range for guaranteed performance.
Part Context
This device belongs to the LMV7235/39 series of comparators designed for space-constrained, battery-operated systems. It shares functional similarities with the LMV7239 but differs in output topology, utilizing an open-drain structure instead of a push-pull arrangement. This distinction necessitates different external circuitry considerations for output driving capabilities.
Replacement Considerations
The LMV7235M7X/NOPB serves as a direct pin-compatible alternative packaged in SC-70-5. Verify that the reduced physical footprint of the SC-70-5 package aligns with the PCB layout requirements. Electrical characteristics remain consistent between the SOT-23 and SC-70-5 variants within the same series.
