MAXIM MAX4995A/AF/AL/MAX4995B/MAX4995C Manual
The MAX4995 family (MAX4995A, AF, AL, B, C) are programmable current‑limit switches that protect host devices from over‑current conditions. They operate from a 1.7 V to 5.5 V supply, provide a selectable current limit of 50 mA to 600 mA, and feature a low 130 mΩ typical on‑resistance.
The devices are offered in three compact packages (10‑pin UTQFN, 6‑pin SOT23, 8‑pin TDFN) and operate over an extended temperature range of –40 °C to +125 °C. Different part numbers implement distinct over‑current responses: autoretry (A/AF/AL), latch‑off (B), and continuous limit (C). Integrated protections include thermal shutdown, reverse‑current protection, short‑circuit protection, and an overload flag.
