REV 0.5 100511
Description
The 9TCS1083 is a highly programmable IC that integrates
clock synthesizers with a PWM Fan controller and multiple
temperature sensors for hardware thermal protection.
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
powered by a CR2032 battery. The 9TCS1083 can output
computer system clock frequencies of 24, 25, 27, and 48
MHz which will reduce 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
operation and will work with multiple pole, brushless DC
fans. An integrated Start-up Timer ensures reliable motor
start-up and turn-on, or following a detected fault condition.
The 9TCS1083 includes a temperature monitor that
measures two diodes. The temperature sensor is optimized
to be accurate within ±1°C within 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 set critical limits. The
hardware limits drive dedicated fault and alert pins for
system shutdown.
The 9TCS1083 is available in a 32-pin QFN package and is
available for commercial temperature range.
