Product Overview

The ADM1029 is a versatile fan controller and monitor for use in personal computers, servers, telecommunications equipment, or high-availibility systems where reliable control and monitoring of multiple cooling fans is required. Each ADM1029 can control the speed of one or two fans and can measure the speed of fans that have a tachometer output. The ADM1029 can also measure the temperature of one or two external sensing diodes or an internal temperature sensor, allowing fan speed to be adjusted to keep system temperature within acceptable limits. The ADM1029 has FAULT inputs for use with fans that can signal failure conditions, and inputs to detect whether or not fans are connected.
