Its supply range spans -80V to -20V, covering the nominal -48V rail plus the transients and dips common on a floating battery plant. The controller draws 700 µA from the negative rail, a quiescent load that stays well under the standby budget of a line card. It does not integrate the series pass FET — that is an external N-channel MOSFET the designer selects based on the load current and thermal budget. ## Programmable fault handling and auto-retry The part supports programmable overvoltage (OVP), undervoltage (UVLO), circuit breaker threshold, and fault timeout. The fault response can be set to latched shutdown, auto-retry, or a timed circuit-breaker cycle — the mode is selected by the external resistor network on the TIMER and UV/OV pins.","metaTitle":"MAX5949AESA+ Hot Swap Controller, -48V, 8-SOIC","metaDescription":"MAX5949AESA+ hot swap controller from Analog Devices, -80V to -20V supply, 700 µA quiescent, active production, ROHS3 compliant.
