EMC2101 Fan Controller The Microchip EMC2101 is a Fan Controller IC that integrates Temperature Monitoring and Fan Speed Control into one device. The device offers the flexibility of Fan Speed Control via a PWM or Linear (DAC) output. Both methods utilise a user customisable fan speed profile contained within the integrated Fan Control Look-Up Table. The temperature monitors, one external and one internal, are also user programmable with adjustable interrupts. The EMC2101 communicates via a SMBus 2.0 compliant interface. In addition to Host controller signals this interface can also be used to connect a SMBus compliant EEPROM for auto-programming the EMC2101 on power-up. Features Automatic Beta Compensation Resistance Error Correction Self-programming with available SMBus compatible EEPROM Selectable PWM or DAC fan driver output External Temperature Monitor with ±1°C accuracy Internal Temperature Monitor with ±2°C accuracy 3.3 Volt Operation (5 Volt Tolerant Input Buffer
