EMC2113-1-AP-TR

Thermal Management Overview

The EMC2113-1-AP-TR is an SMBus compliant fan controller featuring a hardware thermal shutdown mechanism and support for multiple temperature zones. It operates on a 3.3V supply voltage and is housed in a 16-pin 4mm x 4mm QFN package. The device integrates an RPM-based fan speed control algorithm with automatic tachometer feedback, alongside a direct PWM drive setting capability. It includes a programmable temperature look-up table to manage fan speeds based on measured temperatures from up to three external diodes and the internal diode.
