AMC6821SQDBQRQ1 Description

Short technical summary and product information.

The Texas Instruments AMC6821SQDBQRQ1 is an intelligent temperature monitor and pulse-width modulation (PWM) fan controller designed for noise-sensitive or power-sensitive applications requiring active system cooling. This device can simultaneously drive a fan, monitor remote sensor diode temperatures, and measure and control fan speed for minimal acoustic noise.

 

Key electrical specifications include an operating voltage range of 2.7V to 5.5V and a maximum supply current of 2000µA. The local sensor accuracy is ±2°C, with remote sensor accuracy also at ±3°C. Temperature resolution is 0.250°C. The device features a PWM controller with a frequency range of 10 Hz to 40 kHz and a duty cycle from 0% to 100% with 8-bit resolution.

 

It utilizes an SMBus interface and supports up to 9 addresses. The AMC6821SQDBQRQ1 offers automatic fan speed control loops and fault detection. It is qualified for automotive applications with a junction temperature range of -40°C to +150°C.

 

The component is housed in a 16-SSOP package and is designed for surface mount applications. It supports both internal and external sensor types and provides both alarm and fan output signals.
