Input range and quiescent current define the bias rail fit
The MAX8757ETI+ operates from a 4.5V to 26V input rail, covering the common backplane and intermediate bus voltages found in network equipment and telecom line cards. The 25 µA supply current is low enough that the controller can be left biased continuously on a powered backplane without measurable impact on the system standby budget.
Package and board integration for the 28-TQFN
Housed in a 28-WFQFN with exposed pad (5x5 mm body, supplier device package 28-TQFN), the part requires a thermal land on the PCB to sink heat from the internal linear regulators. The surface-mount package is supplied in Bulk tube, not tape-and-reel, which affects pick-and-place feeder setup for medium-to-high volume assembly lines.
Active lifecycle and compliance documentation
No official second-source or pin-compatible alternative is listed in the available records. The part is single-sourced from Analog Devices; for a BOM hedge, confirm the supply position at quote time.
