Notebook power rail sequencing controller
The MAX1977EEI-TG068: It integrates the control logic and drive for sequencing multiple output rails from a single input supply. Operating from a 4.5V to 24V input, it generates two regulated output ranges: a low-voltage rail adjustable from 2V to 3.3V, and a higher-voltage rail from 5V to 5.5V. The four output channels allow it to manage the core, I/O, and peripheral power-up sequence in a portable platform.
The narrow body keeps the board area small, which matters in the tight layout of a notebook motherboard. The surface-mount package suits standard reflow assembly.
Active lifecycle and ordering posture
The ordering code includes the -TG068 suffix, which designates the bulk package format. When specifying this part for a BOM line, confirm the exact ordering code matches the required package quantity — bulk units are typically shipped in tubes or trays, not tape-and-reel.
