The IDT 9TCS 108x devices include a twin channel thermal sensor, pulse width modulation (PWM) fan controller with four wires and a timing sensor with low power all on a single chip thus reducing the cost of materials and providing more free space. The low power timing sensor can provide more battery life and the multiple clock outputs can help in reducing the weight and size of the device as compared to regular on-board crystals. The thermal sensors that have been integrated have an accuracy rate of ±1˚C for overheating detection. Both channels can be programmed separately to trigger a temperature alert. This feature can be used to create an alert for the system as a whole or gather reference data for the fan controller.
The fan controller can be controlled directly without the need for additional control circuits or an interrupting system. The system comes in various frequencies such as 24 MHz, 25 MHz, 48 MHz, 27 MHz and 32.768 MHz with a power consumption of 2 µA in battery mode. Designers can choose whatever device is ideal for their application as the device offers great flexibility in functionality.
