Internal switches on both the high-side and low-side paths allow the controller to break the circuit on fault without relying on an external MOSFET — the 1 mA supply current is the controller's own draw, not the load current. Programmable circuit-breaker threshold, current limit, latched fault, thermal limit, and UVLO are all integrated — the latched fault holds the output off after a trip until the input is cycled, which prevents nuisance auto-retry into a persistent short. ## Industrial temperature range and networking focus Explicitly targeted at networking applications per the manufacturer's classification — the wide input range and latched fault behaviour align with the hot-swap requirements of line cards and redundant power feeds in Ethernet switches and routers. ## 6-TDFN-EP package — thermal and board-fit Surface-mount assembly with a single channel in a compact package — the 6-TDFN-EP suits space-constrained line-card layouts where a separate hot-swap controller and external MOSFET would consume more board area.","metaTitle":"MAX5903LBETT+ Hot Swap Controller, 9V-72V, Simple Swapper™","metaDescription":"MAX5903LBETT+ Analog Devices Hot Swap Controller, 9V-72V supply, internal switches, latched fault & thermal limit.
