9TCS1083BNLG

PRELIMINARY DATASHEET MOBILE ACCESS™—CLOCK SYNTHESIZER, TEMPERATURE SENSOR, & PWM FAN CONTROLLER FOR PORTABLE DEVICES Description Features The 9TCS1083 is a highly programmable IC that integrates clock synthesizers with a PWM Fan controller and multiple temperature sensors for hardware thermal protection. Thermal Sensor • Two temperature sensor channels • Both H/W & S/W programmable over/under temperature The device has an ultra-low-power 32.768 kHz frequency generator to support Real Time Clocks (RTC). This device can generate the 32.768 kHz frequency up to four years of life powered by a CR2032 coincell battery. The 9TCS1083 can output computer system clock frequencies of 24, 25, 27 and 48 MHz which reduces the component count on the circuit board. • • • • The fan controller is pulsed width modulated (PWM) used for the temperature proportional speed control. The device is highly configurable through I2C for ease and flexibility of use. The fan controller has three different modes of operations and will work with multiple pole, brushless DC fans. An integrated Start-up Timer ensures reliable motor start-up and turn-on or follows a detected fault condition. Fan Controller The 9TCS1083 includes temperature monitor function that measures through two external diodes. The temperature sensor is optimized to be accurate within ±1°C between the temperature range of 60°C to 100°C. This device is highly programmable through the use of I2C to set high and low limits for all the temperature channels as well as setting critical limits. The hardware limits drive dedicated ALERT and THERM pins for system shutdown. The 9TCS1083 is available in a 32-pin QFN package and is available for commercial temperature range.
