onsemi Temperature Monitor, Surface Mount, ±2.5°C, 24 Pins

The ADT7490 temperature monitor with fan control is ideal for designs that require economical and minimal noise system cooling. It is designed to;

a) measure and monitor ambient temperature
b) measure and monitor up to 2 remote temperature sensors
c) monitor and control the fan speed of up to 4 fans

The ADT7490 also has the added functionality of series resistance cancellation and the ability to monitor a CPU temperature with it's PECI (platform environmental control interface).

Features;

-3 PWM outputs (High frequency or low frequency)
-4 tachometer inputs
-SMBus serial interface
- 2 GPIO pins
-TMIN control mode
-IMON monitoring
