Product Overview
The MAX31785ETL+ is a 6-channel intelligent fan controller in 40 pin TQFN package. It is a closed-loop multichannel fan controller. Automatic closed-loop fan control saves system power by operating the fans at the lowest possible speeds. Added benefits of slower fan speeds include lower audible noise, longer fan life and reduced system maintenance. Based on a user-programmable lookup table (LUT), the device automatically adjusts the speeds of the six independent fans based on one or more of the 11 available temperature sensors. Alternately, an external host can manually command the fan speeds and the device automatically adjusts the fan speeds. The device contains a fan-health-diagnostic function to help users predict impending fan failures. The device can also monitor up to six remote voltages. Typical applications include network switches/routers, base stations, servers, smart grid network systems and industrial controls.
- Supply voltage range is 2.7V to 5.5V
- Operating temperature range from -40°C to 85°C
- Supports 3-wire and 4-wire fans, automatic closed loop fan speed control
- RPM or PWM based control, optional manual mode control and fast and slow PWM frequency options
- Staggered fan spin-up eases power-supply stress
- Dual tachometer, fan fault detection, fan health status & non-volatile fan operating run time meter
- Available 6-channel ADC to measure remote voltages
- PMBus compliant command interface
- I2C/SMBus compatible serial bus with bus timeout function
- On-board non-volatile fault logging and default configuration setting
