2.3V to 5.5V input, adjustable current limit
The MAX14575CETA+T: This is a high-side current-limiting IC that sits between the supply rail and the load, monitoring current on the positive side rather than the return path. The input range spans 2.3V to 5.5V — a single Li-ion cell at 3.6V nominal through a regulated 5V USB rail all fall inside the operating envelope. The output current is adjustable, not fixed — an external resistor sets the limit threshold. The ±10% accuracy on the limit means the actual trip point can sit 10% above or below the programmed value, so the downstream load must tolerate that guard band without damage.
8-TDFN exposed pad, 2x2 mm — board-fit note
The part comes in an 8-WFDFN package with an exposed thermal pad, supplier device package 8-TDFN-EP measuring 2x2 mm. Available on tape and reel for production pick-and-place, or cut tape for prototype builds. The reel quantity is the standard Analog Devices reel size for this package family.
ROHS3 compliance — no exemption conflicts
The MAX14575CETA+T is ROHS3 compliant, meaning no restricted substances above the threshold limits and no exemption carve-outs that expire on a future date. For EU-market equipment or any BOM that requires full ROHS3 declaration, this part clears without a waiver note.
