MikroE MAX6615 | Demoboard Fan 8 Click
Dual-Channel Temperature Monitors and Fan-Speed Controllers with Thermistor Inputs
Overview
| Topology | Sensors |
| Input voltage | 3.3-5 V |
| IC revision | 1 |
Description
Fan 8 Click is a compact add-on board that represents a compliant fan controller. This board features the MAX6615, a fan-speed controller, and a dual-channel temperature monitor with external thermistor inputs from Analog Devices. The MAX6615 controls the speed of two cooling fans based on the temperatures of external thermistors and the device's internal temperature, reporting temperature values in a digital form using the I2C serial interface. The temperature data controls a PWM output signal to adjust the speed of a cooling fan, minimizing noise when the system is running cool, but providing maximum cooling when power dissipation increases. It also features an overtemperature alarm to generate interrupts, throttle, or shutdown signals. The combination of high accuracy and dual thermistor inputs makes this Click board a practical choice for networking equipment, servers, or other applications requiring cooling and temperature control.
Features
- Two Thermistor Inputs
- Two Open-Drain PWM Outputs for Fan-SpeedControl
- Local Temperature Sensor
- Six GPIOs (MAX6616)
- Programmable Fan-Control Characteristics
- Controlled PWM Rate-of-Change Ensures Unobtrusive Fan-Speed Adjustments
- Fail-Safe System Protection
- OT Output for Throttling or Shutdown
- Nine Different Pin-Programmable SMBus Addresses
- 16-Pin and 24-Pin QSOP Packages
Typical applications
- Temperature Monitor Fan Speed Controller
