LMV7239M5/NOPB

The TI LMV7239M5/NOPB is an automotive-grade, low-power, precision, rail-to-rail input/output (RRIO) comparator. The device features an extended input common-mode range of 1.2V to 24V, and an output voltage of 0V to 6V. It provides a snapshot of the difference between the two inputs and maintains comparator functionality across a wide common-mode voltage range.

The device also offers excellent accuracy over input common-mode voltage range, with a guaranteed common-mode rejection (CMRR) of 70dB and a maximum CMRR of 80dB. It provides a fast output reaction time of 120ns and a high input impedance to minimize loading on the source and reduce the total number of components required for a system.

Application Field: The LMV7239M5/NOPB is suitable for a wide range of applications such as monitoring, detection, and control. It is well-suited for motor control, automotive lighting, battery management systems, and industrial applications. The device is optimized to operate over extended input common-mode voltage range and offer a low-noise output capable of driving microcontrollers and logic.

Working Principle: The LMV7239M5/NOPB features a rail-to-rail input stage that receives the two inputs and compares them. The inputs can be applied to either of the two input pins or both at the same time. The output transitions between 0V to 6V when the two inputs differ by more than an hysteresis setting based on the logic level on the low pin control input (LPCI). It is also capable of producing an adjustable output voltage window using the voltage divider on the VREF pin. The device features an integrated delay to ensure that the output voltage remains stable over its full common-mode input range.

In summary, the LMV7239M5/NOPB is an ideal RRIO linear comparator for a variety of applications. Its extended input common-mode voltage range, low power consumption, and fast response time make it ideal for industrial, automotive and other applications. The device’s output is capable of driving a microcontroller or logic device and its adjustable voltage window can be used to monitor signals and detect levels. The LMV7239M5/NOPB is an ideal solution for applications requiring a comparator with excellent accuracy, accuracy over extended common-mode voltage range, fast response time, and low-noise output.
