What the MAX4766AETA is and where it fits
The Maxim MAX4766AETA is a programmable current-limit switch, designed to protect power rails in USB ports, hot-swap controllers, and general-purpose power-distribution applications. Its key feature is the ability to set the current-limit threshold with an external resistor, giving the designer flexibility to match the load without changing the IC.
RoHS non-compliance — what it means for your BOM
The MAX4766AETA is RoHS non-compliant, which restricts its use in designs that must meet EU RoHS or similar environmental directives. For legacy products with an existing exemption, or for non-consumer applications where leaded solder is still permitted, this part remains a valid choice.
Sourcing and availability
The MAX4766AETA is sourced through independent distribution and quoted to order against an RFQ. Because the part is active, there is no last-time-buy pressure, but the RoHS restriction may narrow the pool of available stock over time as manufacturers shift to compliant variants.
