Microchip EMC2103-2-AP-TR Motor Driver IC, 3.3 V NoneA 16-Pin, VQFN

The Microchip EMC2103 is a family of Fan Controller ICs that integrate 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 include an RPM based FAN Speed Algorithm as part of an integrated Fan Control Look-Up Table. This table can be user customised to prescribe the desired fan speed based on the temperature channel inputs.

Programmable Fan Control Circuit: 4-wire fan compatible, high and low frequency PWM
RPM Based Fan Control Algorithm: 2.5% accuracy from 500 RPM to 16k RPM, detects fan aging and variation
Temperature Look-Up Table: Controls fan speed (RPM) or PWM drive setting
One Internal Temperature Channel: ±1°C accuracy, 0.125°C resolution
One External Temperature Channel (EMC2103-1 model only): ±0.5°C accuracy, 0.125°C
Three External Temperature Channels (EMC2103-2 and EMC2103-4 models only): ±0.5°C accuracy, 0.125°C
Hardware Programmable Thermal Shutdown Temperature: 65°C to 127°C range
Programmable High and Low Limits for all channels
SMBus 2.0 Compliant
Two dedicated GPIOs (EMC2103-2 and EMC2103-4 models only)
EEPROM Auto-Programming on Power-Up (EMC2103-4 model only)
