Visão Geral

Description

The LMV331M5X/NOPB is Texas Instrument’s low-power, single-channel voltage comparator. It compares two input voltages and provides a digital-like output indicating which input is higher, suitable for thresholding in battery-powered and space-constrained designs. Key points: wide operating supply range (low-voltage operation), low quiescent current, fast response, and a compact package. The M5X suffix denotes the specific packaging/temperature variant, while NOPB meansPb-free (lead-free) packaging. Typical applications include battery monitoring, level detection, zero-cross detectors, watchdogs, and simple power-supply monitoring or control loops. In short: a compact, energy-efficient comparator for fast, simple thresholding tasks in low-power systems.

Equivalent

Possible equivalents (functionally similar, check pinout/packaging):
- TLV331 (Texas Instruments) – same family, rail-to-rail input/output
- TSV331 (STMicroelectronics) – cross-family low-voltage comparator
- MCP6541 / MCP6542 (Microchip) – low-power, single-supply comparators with similar IO
Note: exact pinout and performance may vary by vendor; verify datasheets and packaging before substitution.

Features

Here are the key features of LMV331M5X/NOPB:
- Single-supply operation: 2.7 V to 5.5 V
- Input common-mode range includes ground (up to about Vcc − 1.2 V)
- Output is open-collector (NPN); requires an external pull-up resistor
- Low quiescent current and low-power operation
- High-speed comparator type for fast threshold detection
- Wide temperature range: -40°C to 125°C
- 5-pin SC-70 / SOT-23 package; RoHS-compliant (NOPB)
- Suitable for battery-powered and threshold-detection applications (zero-crossing, level shifting, window comparators)
Note: For exact electrical specs (offset, propagation delay, sink current, etc.), refer to the datasheet.

Pinout

Pin count: 5 pins. Function: Single-channel, low-voltage comparator (LMV331). Pinout (SC-70/SOT-23-5): Pin 1 = Output, Pin 2 = Non-Inverting input (+), Pin 3 = Inverting input (−), Pin 4 = Vcc, Pin 5 = GND.

Manufacturer
