The MAX31790ATI is a versatile fan controller designed by Analog Devices / Maxim Integrated for applications requiring precise control and monitoring of multiple fans. It features six independent PWM outputs that can directly drive 4-wire fans or modulate fan speed via an external pass transistor. The device includes tachometer inputs for accurate RPM monitoring and fan failure detection.
With an operating voltage range of 3.0V to 5.5V and an I2C-compatible interface, the MAX31790ATI is suitable for a wide array of cooling applications. It offers controlled duty cycle rate-of-change for reduced acoustic impact and versatile startup configurations for reliable fan operation at power-up. The operating temperature range is -40°C to +125°C.
Key features include up to 12 tachometer inputs, I2C bus interface with timeout and watchdog, and controlled duty cycle rate-of-change for optimal acoustics. The MAX31790ATI is available in a 28-pin TQFN package, making it ideal for integration into compact systems.
Applications for this fan controller include servers, networking equipment, and telecommunications infrastructure where efficient and reliable thermal management is critical.
