The EMC2103-4-AP-TR is a RPM-based Fan Controller with hardware thermal shutdown. The EMC2103 is a SMBus fan controller with up to up to 3 external and 1 internal temperature channels. The fan driver can be operated using two methods each with two modes. The methods include an RPM based fan speed control algorithm and a direct PWM drive setting. The modes include manually programming the desired settings or using the internal programmable temperature look-up table to select the desired setting based on measured temperature. The temperature monitors offer ±0.5°C accuracy with sophisticated features to reduce errors introduced by series resistance and beta variation of substrate thermal diode transistors commonly found in processors. The EMC2103 also includes a hardware programmable temperature limit and dedicated system shutdown output for thermal protection of critical circuitry.

• High and low frequency PWM
• RPM based fan control algorithm - Detects fan aging and variation
• Temperature look-up table - Supports DTS data from CPU
• Allows programmed fan response to temperature
• Controls fan speed or PWM drive setting
• Allows externally set temperature data to drive fan
• Automatically detects and supports CPUs requiring the BJT or transistor models
• Resistance error correction
• Supports discrete transistors
• Hardware programmable thermal shutdown temperature - Cannot be altered by software

• Programmable high and low limits for all channels
• Two dedicated GPIOs
