Hot Swap Controllers
Hot swap controllers are power management ICs used to safely insert or remove circuit boards and modules while a system remains powered. They provide functions such as inrush current control, fault protection, current limiting, voltage monitoring, and power sequencing, and are commonly used in servers, telecom equipment, storage systems, industrial power supplies, networking devices, and high-availability electronic systems.
TomatoElec is an independent electronic components distributor supplying hot swap controller 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 hot swap controller sourcing support.
