The Texas Instruments AMC6821SDBQ is an integrated temperature monitor and PWM fan controller designed for noise-sensitive and power-sensitive applications requiring active system cooling. This device operates within a supply voltage range of 2.7V to 5.5V and communicates via an SMBus interface.
It offers both internal and external temperature sensing capabilities with an accuracy of ±2°C and a resolution of 0.125°C. The AMC6821SDBQ includes a PWM controller with a frequency range of 10Hz to 40kHz and an 8-bit duty cycle control, allowing for automatic fan speed regulation to minimize acoustic noise. The operating temperature range for this component is -40°C to 125°C.
Packaged in a 16-SSOP (QSOP-16) surface-mount configuration, the AMC6821SDBQ is suitable for applications such as notebook and desktop PCs, network servers, and telecommunications equipment. It provides features like an output alarm and fan control, making it a versatile solution for thermal management.
Key specifications include a maximum supply current of 2000µA and the ability to monitor remote sensor diodes. The device supports multiple addresses, enhancing its integration into complex systems.
