LM3822MMX-2.0

Current Regulation/Management Overview

The LM3822MMX-2.0 is a high-side current gauge regulator manufactured by Texas Instruments, designed for precise current monitoring in power management applications. It operates within an input voltage range of 2V to 5.5V and provides a current measurement accuracy of ±2%. The device utilizes a high-side sensing method to monitor load current without requiring low-side ground references. Packaged in an 8-VSSOP (also referred to as 8-MSOP) surface-mount package, it integrates the necessary circuitry for accurate current regulation and feedback. This component is suitable for battery-powered systems and portable electronics where space efficiency and measurement precision are critical.
