EMC2101 SMBus Fan Control with 1°C Accurate Temperature Monitoring PRODUCT Features General Description The EMC2101 is an SMBus 2.0 pliant, integrated fan control solution plete with two temperature monitors, one external and one internal. Each temperature channel has programmable high limits that can assert an interrupt. The fan drive is selectable as a Pulse Width Modulator (PWM) or Linear (DAC) output. The fan control output, whether the PWM or DAC drive circuit, uses an eight position look-up table to allow the user to program the fan speed profile based on temperature. The DAC output ranges from 0V to VDD with up to 6 bit resolution while the PWM output has a range...
