Prezentare generală a produsului

The EMC2104-BP-TR is a dual RPM-based PWM Fan Controller with hardware thermal shutdown. The SMBus compliant fan controller with up to five 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 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 1°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 EMC2104 also includes hardware programmable temperature limits and dedicated system shutdown output for thermal protection of critical circuitry.
  • Two programmable fan control circuits - 4-wire fan compatible
  • High and low speed PWM
  • Temperature look-up table - Controls fan speed or drive setting
  • Allows programmed fan response to temperature
  • 1 to 4 Thermal zones to control each fan driver
  • Allows externally generated temperature data to control fan driver including two DTS channels
  • Automatically detects and supports CPUs requiring the BJT or transistor models
  • Resistance error correction
  • Detects fan aging and variation
  • Up to three thermistor compatible voltage inputs
  • Hardware programmable thermal shutdown temperature - Cannot be altered by software
  • Programmable high and low limits for all channels
