Each output delivers up to 1.5A continuous from a 2.7V to 5.5V load supply — covering both 5V USB ports and 3.3V peripheral rails. Typical on-resistance is 80 mOhm per channel. At 1.5A that's about 180 mW of dissipation per channel — the 16-TSSOP copper pad on the PCB carries that heat, so the board layout matters more than the package itself for staying under the 85°C ambient ceiling. ## Protection set — adjustable current limit, over-temp, reverse current Fault protection includes adjustable current limiting (set via an external resistor), over-temperature shutdown, and reverse-current blocking. The reverse-current block is the one that catches people — if the USB port voltage rises above the input rail (say a powered hub back-feeds), the switch opens instead of back-driving the bus. The On/Off control input is non-inverting and needs no external Vcc supply — the switch is enabled by pulling the EN pin high. A Status Flag output signals over-current or thermal fault conditions. ## Active production — sourcing for the BOM line The part is RoHS non-compliant per the manufacturer listing. If your BOM requires RoHS conformance, check the -1 or -2 suffix variants in the MIC2547 family — the base part number without the suffix is the non-compliant version.","metaTitle":"MIC2547-2BTSTR USB Switch, Dual 1.5A, 80mOhm, 16-TSSOP","metaDescription":"Microchip MIC2547-2BTSTR dual high-side USB switch, 1.5A per channel, 80mOhm Rds(on), adjustable current limit, active production.
