The MAX31790ATI+T is a versatile fan controller IC designed by Analog Devices / Maxim Integrated for precise fan speed control and monitoring in applications requiring multiple fans. It features six independent PWM outputs capable of controlling fan speeds, with desired speeds set via an I2C interface. The device includes tachometer inputs for accurate RPM monitoring and fan failure detection.
With a supply voltage range of 3.0V to 5.5V, the MAX31790ATI+T is suitable for a wide array of cooling applications. It operates within a temperature range of -40°C to +125°C. The IC is available in a compact 28-TQFN (4x4) package, making it ideal for space-constrained designs. Its controlled duty cycle rate-of-change ensures low acoustic impact, enhancing system reliability and user experience.
Key features include up to 12 tachometer inputs, versatile startup configurations for reliable fan control at power-up, and an I2C bus interface with timeout and watchdog functionalities. This makes the MAX31790ATI+T an excellent choice for demanding applications in servers, networking equipment, and telecommunications infrastructure where efficient and reliable thermal management is critical.
The device is surface-mount compatible and comes in a 28-WFQFN exposed pad package. Its integrated control and power stage simplifies design, reducing external component count. The I2C interface allows for easy integration with microcontrollers, enabling dynamic fan speed adjustments based on system load and temperature.
