Application Field and Working Principle of LM4140ACMX-2.0/NOPB

Power Management ICs, such as voltage references, are special integrated circuits used to help deliver power to vital systems within the smallest footprint possible. The LM4140ACMX-2.0/NOPB is a high-performance voltage reference and voltage comparator designed to provide a wide range of voltage references and comparing tasks. This power Management IC (PMIC) provides an adjustable output voltage of up to 3.2 V, and provides excellent accuracy, stability, fast settling time, low power consumption, and low voltage noise.The LM4140ACMX-2.0/NOPB makes use of a proprietary monolithic voltage reference circuit, the LM413 Reference Generator, to accurately compare and generate voltage references. This reference generator uses a temperature-compensated voltage reference integrated circuit (VREF IC) to maintain accurate reference levels, even under changes in temperature or load. This results in an adjustable output voltage of up to 3.2V.The LM4140ACMX-2.0/NOPB includes an adjustable output resistor to adjust the output voltage level. This voltage comparator can be used to detect over-voltage and under-voltage using different voltage thresholds, allowing for excellent protection from over-voltage and under-voltage. Additionally, the LM4140ACMX-2.0/NOPB features an adjustable output current limit capability, allowing for current limiting to protect load-generating circuits from excessive current levels.The LM4140ACMX-2.0/NOPB is designed to provide a wide range of voltage options, ranging from 1.2V to 3.2V. With its low power consumption, high accuracy, and a 0.5 % accuracy level, this power management IC can be used in many different applications, from portable devices to automotive applications. Additionally, the LM4140ACMX-2.0/NOPB can be used to provide an onboard voltage reference for mobile or portable devices, or as a voltage comparator for system-level displays, controllers, and servers.In summary, the LM4140ACMX-2.0/NOPB voltage reference is a high-performance power management IC (PMIC) designed to provide a wide range of voltage options, excellent accuracy, and low power consumption. The adjustable output resistor allows users to adjust the output voltage level, while the voltage comparator can be used to detect over-voltage and under-voltage. The LM4140ACMX-2.0/NOPB is suitable for a variety of applications, from portable devices to automotive systems.
