No internal switch — the FET is external, so the thermal rise of the pass element is managed at the board level, not inside the controller package. Supplied in a 12-lead TSSOP (3.00 mm width) which also maps to the 12-MSOP supplier device package — the same footprint, so either marking on the reel matches the same land pattern.","metaTitle":"LTC4231IMS-2#PBF Hot Swap Controller, 2.7-36V, 12-MSOP","metaDescription":"Active LTC4231IMS-2#PBF hot swap controller from Analog Devices. 2.7-36V supply, 4 µA quiescent, programmable features. 12-MSOP.
