Current Regulation/Management

Current regulation and management ICs are power management devices used to control, monitor, limit, or stabilize current flow in electronic circuits. They are commonly used for LED driving, battery charging, load protection, motor control, power supplies, industrial equipment, automotive electronics, communication systems, and embedded applications.

TomatoElec is an independent electronic components distributor supplying current regulation and management ICs from mainstream manufacturers such as Texas Instruments, Analog Devices, STMicroelectronics, onsemi, Infineon, Microchip, Renesas, NXP, Diodes Incorporated, and Monolithic Power Systems. Customers can check inventory, price, package, specifications, parameters and PDF datasheets in the product list below, and submit a BOM or RFQ for current regulation and management sourcing support.
