The Maxim Integrated MAX6512UT085 is a remote temperature switch designed to monitor the temperature of an external diode-connected transistor, typically a CPU, GPU, or FPGA die. It asserts an open-drain output when the remote temperature exceeds a factory-programmed threshold. This part is used in thermal management systems for servers, telecom equipment, and industrial controllers where accurate die-temperature monitoring is needed without placing the sensor directly on the hot substrate.
This excludes it from designs that must meet EU RoHS or similar regulatory requirements. For legacy production, mil/aero, or high-reliability applications where RoHS exemption applies, this part remains a valid choice. If your BOM requires RoHS compliance, you will need to source an equivalent that meets that standard.
