AMC6821SDBQR Description

Short technical summary and product information.

The AMC6821SDBQR from Texas Instruments is an intelligent temperature monitor and pulse-width modulation (PWM) fan controller designed for noise-sensitive and power-sensitive applications requiring active system cooling.

 

This device integrates a tachometer and a 2-channel temperature sensor. It can monitor remote sensor diode temperatures and measure/control fan speed to minimize acoustic noise. Key electrical specifications include an SMBus interface, a supply voltage range of 2.7V to 5.5V, and a maximum supply current of 2000µA.

 

The temperature sensing capabilities offer local and remote sensor accuracy of ±2°C with a resolution of 0.125°C. The PWM controller supports frequencies from 10Hz to 40kHz with an 8-bit duty cycle control from 0% to 100%. Automatic fan speed control loops are also included.

 

Packaged in a 16-SSOP (0.154", 3.90mm Width) surface-mount configuration, the AMC6821SDBQR is suitable for applications such as notebook and desktop PCs, network servers, and telecommunications equipment.
