EMC6D103
For product comparison, please consider:
The EMC6D103 is an environmental monitoring device with automatic fan control capability. This ACPI compliant device provides hardware monitoring for up to five voltages 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 EMC6D103 hardware monitor provides analog inputs for monitoring external voltages of +2.5V, +5V, +12V and 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.
The EMC6D103 hardware monitor includes support for monitoring three thermal zones: two external and one internal. The external temperatures are measured via thermal diode inputs capable of monitoring remote devices. In addition, they are equipped with an ambient temperature sensor for measuring the internal temperature.
Pulse Width Modulators (PWM) control the speed of the fans by varying the output duty cycle of the PWM. Each PWM can be associated with any or all of the thermal zones monitored. As the temperature of the associated zone varies, the PWM duty cycle is adjusted accordingly. The Ramp Rate Control feature controls the rate of change of the PWM output, thereby reducing system noise created by changing the fan speed. The speed of each fan is monitored by a Fan Tachometer input. The measured values are compared to values stored in Limit Registers to detect if a fan has stalled or seized.
Fan speed may be under host software control or automatic. In host control mode, the host software continuously monitors temperature and fan speed registers, makes decisions as to desired fan speed and sets the PWM's to drive the required fan speed. This device offers an interrupt output signal (INT#), which may be used to interrupt the host on out-of-limit temperature or voltage condition enabling an ACPI response as opposed to the host software continuously monitoring status. In auto "zone" mode, the logic continuously monitors the temperature and fan speeds and adjusts speeds without intervention from the host CPU. Fan speed is adjusted according to an algorithm using the temperature measured in the selected zone, the high and low limits set by the user, and the current fan speed.
