The ADM1030ARQZ-REEL by ON Semiconductor is an intelligent temperature monitor and PWM fan controller designed for computers and thermal management systems. It features ACPI compliance and is optimized for Pentium III processors, allowing for reduced temperature guardbanding and increased system performance.
This device offers two channels for digital temperature monitoring, with one input dedicated to a remote temperature-sensing diode accurate to ±1°C and a local sensor for ambient temperature monitoring. The ADM1030ARQZ-REEL provides a Pulsewidth Modulated (PWM) fan control output that varies the fan speed by adjusting the output duty cycle between 33% and 100%. Fan speed can be monitored via a TACH input, and the device can detect a stalled fan. A dedicated Fan Speed Control Loop ensures fan control even if the CPU locks up, and it minimizes acoustic noise and battery consumption.
Key electrical specifications include a supply voltage range of 3V to 5.5V and an operating temperature range of 0°C to 100°C. The device communicates via SMBus and features programmable INT and FAN_FAULT outputs for error conditions and fan failure signaling, respectively. The THERM pin serves as a fail-safe output for over-temperature conditions.
The ADM1030ARQZ-REEL is available in a 16-QSOP package and is suitable for surface mount applications. Its applications include notebook PCs, network servers, and telecommunications equipment.
