MAXIM MAX1823/MAX1823A/MAX1823B/MAX1823H handbook
The MAX1823 family provides a dual, current‑limited USB switch that automatically latches off on a short‑circuit and restores power when the fault clears. Each channel supplies up to 720 mA, features built‑in thermal‑overload protection, a 20 ms fault‑blanking interval, and independent FAULT_ indicator outputs.
The device operates from a 4.0 V to 5.5 V supply, consumes only 50 µA quiescent current (both channels on) and 100 µA in standby, and is packaged in a space‑saving 10‑pin µMAX footprint. Variants MAX1823A/B block reverse current when disabled, and the part is rated for –40 °C to +85 °C operation.
