Overview
EMC2104 Dual RPM-Based PWM Fan Controller with Hardware Thermal Shutdown PRODUCT FEATURES Datasheet General Description The EMC2104 is an SMBus compliant fan controller with up to five (up to 4 external and 1 internal) temperature channels.
The fan drivers can be operated using two methods each with two modes.
The methods include an RPM based Fan Speed Control Algorithm and a direct drive setting.
The modes include manually programming the desired settings or using the internal programmable temperature look-up table to select the desired setting based on measured temperature.
The temperature monitors offer 1°C accuracy (for external diodes) with sophisticated features to reduce errors introduced by series resistance and beta variation of substrate thermal diode transistors commonly found in processors.
The EMC2104 also includes a hardware programmable temperature limitS and dedicated system shutdown output for thermal protection of critical circuitry.
