The 700 µA supply current is the controller's own draw, not the load current — the part has no internal switch, so the pass FET is external and sized for the actual load. Programmable features include circuit breaker, current limit, overvoltage protection (OVP), and undervoltage lockout (UVLO), plus an auto-retry and fault timeout. That means you set the trip thresholds and retry behavior with external resistors — no firmware, just analog. ## Thermal and board-fit note The thermal limit feature protects the external FET, but the controller itself stays cool at 700 µA — no heatsinking needed on the SOIC.","metaTitle":"MAX5921FESA+T Hot Swap Controller, -48V, 8-SOIC, Active","metaDescription":"MAX5921FESA+T hot swap controller from Analog Devices, -80V to -20V supply, 700 µA supply current, 8-SOIC, active production, ROHS3 compliant.
