EMC6D103S Fan Control Device With High Frequency PWM Support And Hardware Monitoring Features

The EMC6D103S is an environmental monitoring device with Automatic fan control capability. This ACPI compliant device provides hardware monitoring for up to fivevoltages and three thermal zones, measures the speed of up to four fans, and controls the speed of multiple DC fans using Pulse Width Modulator (PWM) outputs. High frequency and low frequency PWMs are supported. The EMC6D103S hardware monitor provides Analog inputs for monitoring external voltages of +2.5V, +5V, +12V and the processor voltage Vccp. This device has the capability to monitor its own internal VCC power supply, which may be connected to either main power (VCC) or the suspend power well (VTR). In addition to monitoring the processor voltage, VID inputs are available to identify the voltage specification. External components are not required for voltage scaling or similar treatment.
