Frequently Asked Questions
What interface does the AMC6821SDBQ use for communication?
The AMC6821SDBQ uses an I2C-compatible serial interface, allowing it to communicate with a host processor or system management controller. This enables reading temperature data, configuring fan speed lookup tables, and monitoring fan status registers over a standard two-wire bus at speeds up to 400 kHz.
What type of fan control does the AMC6821SDBQ support?
The AMC6821SDBQ supports automatic closed-loop PWM fan speed control based on measured temperature. It features a programmable lookup table with up to 8 temperature-to-duty-cycle entries, allowing the fan speed to scale smoothly from a configurable minimum speed up to 100% duty cycle as temperature rises.
What are typical applications for the AMC6821SDBQ?
The AMC6821SDBQ is commonly used in servers, workstations, networking switches, and industrial computing platforms where thermal management is critical. It automates fan speed regulation to minimize noise at low loads while ensuring adequate cooling under high-power conditions, reducing system complexity and microcontroller overhead.
How can I purchase the AMC6821SDBQ and what is the price?
The AMC6821SDBQ is available from authorized distributors starting at approximately $2.23 per unit. It is supplied in a small DBQ package. You can submit a request for quote on FindMyChip to receive competitive pricing and confirm stock availability with worldwide shipping options.
