That means it can sit in a ruggedized laptop, a test instrument, or a portable base station without derating for heat soak. The surface-mount SSOP package is standard for reflow assembly; no special handling beyond normal MSL precautions. ## Sourcing and lifecycle Listed as Active on the lifecycle record and RoHS3 compliant. No end-of-life notice or last-time-buy window is flagged, so this part is safe to qualify into a new BOM or sustain an existing production line.","metaTitle":"MAX1901EAI+ Dual-Output Notebook Power Controller, 28-SSOP","metaDescription":"MAX1901EAI+ dual-output PWM controller for notebook power systems.
