It integrates both internal switches and draws 1 mA supply current, keeping the quiescent load off the bus. Programmable protection features include circuit breaker, current limit, latched fault, thermal limit, and undervoltage lockout (UVLO) — all configurable with external resistors, so the trip thresholds match the load's inrush profile. The controller is rated for networking applications and operates over the industrial temperature range of -40°C to 85°C, suitable for outdoor telecom cabinets and factory-floor enclosures where the backplane bus can sag or surge. ## Supply voltage and package Supply voltage range is 9V to 72V. The SOT-23-6 package (supplier device package SOT-23-6) keeps the footprint small for dense line cards. ## RoHS and compliance The MAX5903LBEUT-T is RoHS non-compliant. Verify your assembly house's exemption policy or plan for a lead-bearing solder process.","metaTitle":"MAX5903LBEUT-T Hot Swap Controller, Simple Swapper™, 9V-72V","metaDescription":"MAX5903LBEUT-T hot swap controller from Maxim Integrated. 9V to 72V supply, SOT-23-6, programmable UVLO/current limit, industrial temp.
