Operating from an 18 V to 67 V supply rail, it draws only 400 µA of supply current, keeping the overhead low for the downstream DC-DC converter. ## Package, mounting, and temperature grade No internal switch is integrated — the controller drives an external MOSFET and sense resistor, giving the designer flexibility to match the switch to the load current. ## Lifecycle and compliance status No auxiliary sense input is provided — this is a basic PD controller for standard 802.3af applications without signature detection override.","metaTitle":"MAX5942ACSE+ PoE PD Controller, 12.95 W, 16-SOIC","metaDescription":"MAX5942ACSE+ IEEE 802.3af PoE PD controller, 12.95 W max, 18-67 V supply, 400 µA quiescent, 16-SOIC.
