LMV7239M5 Typical application Circuitry

LMV7239M5

LMV7239M5 is a low-voltage, low-power comparator from Texas Instruments, housed in a compact SOT-23-5 package. It is designed for applications requiring voltage level detection, signal conditioning, or for use in simple analog-to-digital conversion circuits. The device operates with a supply voltage ranging from 2.7V to 5.5V, making it ideal for battery-powered and portable applications due to its low power consumption.

Application Scenario

A common application for LMV7239M5 is in a battery voltage monitoring circuit within a portable device. In this scenario, the LMV7239M5 can compare the battery voltage to a reference voltage to indicate when the battery level is low.

Parameter Features

- Supply Voltage Range: 2.7V to 5.5V, suitable for a variety of low-voltage applications.

- Low Power Consumption: Ideal for extending battery life in portable devices.

- Output Type: Open-drain output, which allows for wired-OR configurations and easy interfacing with different logic levels.

- Package: Available in a small SOT-23-5 package, optimizing board space.

Circuit Design Considerations

Designing with LMV7239M5 involves ensuring the input signals are within the supply voltage range, selecting appropriate pull-up resistors for the open-drain output, and considering the power supply stability and noise immunity.

Detailed Circuit Connection

- Power Supply Connection

Connect a stable power supply within the 2.7V to 5.5V range to the VCC pin (pin 5) of LMV7239M5. This ensures the comparator operates within its specified voltage range.

- Reference Voltage Setup

Set up a reference voltage using a voltage divider or a precision reference source connected to the non-inverting input (IN+) pin (pin 3). This voltage will serve as the threshold for battery voltage monitoring.

- Battery Voltage Monitoring

Connect the battery voltage, possibly through a voltage divider to scale it within the operating range, to the inverting input (IN-) pin (pin 2). This allows LMV7239M5 to compare the battery voltage against the reference voltage.

- Output Configuration

The OUT pin (pin 1) is an open-drain output. Connect a pull-up resistor to this pin, going to VCC or another desired voltage level within the LMV7239M5's operating range. This resistor pulls the output high when the comparator's output is in the high-impedance state.

- Ground Connection

Ensure the GND pin (pin 4) is connected to the system's ground. A solid ground connection is crucial for the stable operation of the comparator.

When designing circuits with LMV7239M5, it's important to carefully consider the choice of the pull-up resistor for the open-drain output to ensure compatibility with the rest of the system's logic levels. Additionally, the voltage divider for the battery voltage (if used) must be designed to not only scale the voltage within the comparator's input range but also to minimize power consumption, which is especially critical in battery-powered applications. Ensuring clean, noise-free power and signal lines will contribute to the reliable operation of the comparator in voltage monitoring applications.
