EMC2105中文资料Single Linear Fan Controller with Thermal Mgt数据手册Microchip规格书

描述 Description

The EMC2105 is an SMBus compliant fan controller with up to five (up to 4 external and 1 internal) temperature channels. The fan driver 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 EMC2105 also includes a hardware programmable temperature limit and dedicated system shutdown output for thermal protection of critical circuitry.
