Current Regulation/Management
Current Regulation/Management ICs are a semiconductor device designed to monitor and regulate current within a circuit. The functions are current gauge, current limiting, current mirror, current monitor, current regulator, current ripple suppressor, current sense, current source, current switch, and an electronic fuse with a current output of adjustable, and 100µA to 50A.
Sourcing STMicroelectronics Current Regulation/Management: in-stock lines for quick ship, BOM matching for multi-line builds, and original-channel screening — not keyword stuffing.
