The MAX6620ATI+ is a quad linear fan-speed controller designed to manage the speeds of up to four independent fans. It utilizes four linear voltage outputs controlled via an I2C interface, allowing for direct drive voltage adjustment. Each output can drive the base of an external bipolar transistor or the gate of a FET in a high-side configuration.
This controller offers two primary fan control methods: RPM mode for precise (±1%) fan speed control and failure detection, and DAC mode with 9-bit voltage resolution. It operates over a wide 3.0V to 5.5V supply voltage range with a low typical operating current of 250µA. The device includes features like DAC_START for controlled startup voltage and a watchdog timer to ensure fan operation during communication loss.
Packaged in a compact 28-pin TQFN (5mm x 5mm) with an exposed pad, the MAX6620ATI+ is suitable for space-constrained applications. It operates across an automotive temperature range of -40°C to +125°C, making it ideal for consumer products, servers, communications equipment, and storage equipment requiring reliable cooling solutions.
