It uses an external N-channel MOSFET (no internal switch) so you size the pass element to your load. The controller draws 600 µA from the rail and operates over the industrial temperature range of -40°C to 85°C, making it a fit for outdoor telecom cabinets, factory-floor motor drives, and any backplane that sees a cold start. ## Package and mounting You get five programmable protection modes: auto retry, circuit breaker, current limit, fault timeout, and latched fault. The circuit breaker threshold and current limit set the trip point for the external MOSFET; the fault timeout decides how long the controller waits before retrying or latching off. On a production line, you set these with a resistor divider and a capacitor — no firmware, no I²C. For a field-service swap, the part is self-contained: pull the old one, drop in the new one, and the protection profile stays the same because the passives on the board set it. ## Package and footprint The MAX4273EEE+ comes in a 16-pin QSOP (also listed as 16-SSOP with 0.154\" body width, 3.90 mm). It is a surface-mount part, so you need a reflow station or a hot-air pencil to swap it on site — not a socketed drop-in. The 0.65 mm pitch is fine for hand soldering with a fine tip and magnification, but the QSOP body is small enough that orientation marking (pin 1 dot) is critical. Double-check the silkscreen before you place it; a 180° rotation on a hot swap controller means the gate drive pin goes to ground and the part won't work. ## Lifecycle and sourcing It is ROHS3 compliant. If you need a datasheet for your review, we can provide it with the quote.","metaTitle":"MAX4273EEE+ Hot Swap Controller, 2.7V–13.2V, 16-QSOP","metaDescription":"MAX4273EEE+ hot swap controller from Analog Devices.
