The STEF48H28 is a 30 A integrated e-fuse for 9-80 V DC power rails. It provides inrush control, undervoltage/overvoltage lockout and overcurrent protection using an adaptive (I x t) scheme that permits short high-current pulses typical of CPU/GPU loads.
The device offers an analog current-monitor output and an on-chip temperature-monitor signal for system supervision. Startup behavior is programmable through insertion-delay and soft-start settings.
Additional features include power-good indication, self-diagnostics, thermal shutdown and a PMBus interface for telemetry and status reporting.
The driver supports standard PMBus driver platform data.
