Description

The LMV331M7/NOPB is a Texas Instruments single-channel, low-power voltage comparator from the LMV family. It’s designed for low-voltage, battery-powered applications and offers a wide input common-mode range that typically includes the negative rail, allowing direct sensing near ground. The M7 suffix indicates a specific package/temperature grade, while NOPB means Pb-free (no lead) packaging. Key uses include threshold detection, zero-/over-/under-voltage sensing, window detection, and other digital signaling where a fast, low-power comparator is beneficial. For exact electrical specs (supply range, input offset, propagation delay, output type, and recommended operating conditions), consult the TI datasheet for the LMV331M7/NOPB.

Features

Concise features of LMV331M7/NOPB:
- Single-channel, low-power voltage comparator
- Supply voltage: 2.7 V to 5.5 V (wide, battery-friendly)
- Input: common-mode range includes ground
- Output: open-drain; requires external pull-up; allows wired-OR logic
- Low quiescent current for battery-powered apps
- Wide operating temperature (typical -40°C to 125°C)
- Pb-free package: M7 (SC-70/5) surface-mount
- RoHS-compliant; suitable for low-voltage, space-saving designs
- Fast response for timing/level-detection tasks
- Applications: level shifting, zero-cross/detection, window detection, battery monitoring
Note: Output high level determined by pull-up resistor; not a rail-to-rail output.

Package

SC-70-5 (5-pin) package, lead-free (NOPB).

Pinout

- Pin count: 8 pins (MSOP-8/SOIC-8 package variants).
- Function: Single-supply voltage comparator (LMV331 family) that compares noninverting and inverting inputs and provides a digital output.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: American multinational semiconductor company specializing in analog and mixed-signal integrated circuits, microcontrollers, sensors, and related electronics.

Application

General-purpose, low-power comparator for single-supply operation. Common applications include:
- Battery-powered portable devices for voltage monitoring and protection
- Threshold detection, hysteresis and window detector networks
- Zero-crossing/line-detection in power supplies
- PWM/regulator and motor-control feedback loops
- Sensor conditioning and microcontroller interfacing

Equivalent

Equivalents:
- TLV331 (TI) – direct device family replacement
- TSV331 (STMicroelectronics)
- NCV331 (ON Semiconductor)
Note: verify pinout and package (M7, NOPB) compatibility before substituting.
