Model TC646EUA
Description TC646 The Microchip TC646 fan controller is a switch mode fan speed controller designed to be used with brushless DC fans. TC646 provides temperature proportional fan speed control through PWM from an external thermistor (or other voltage output sensor). Has a user programmable minimum temperature setting. This allows customization of TC646, and the minimum temperature threshold below the fan will be turned off. Integrated start-up timer for reliable motor start-up. This device can also utilize Microchip FanSense ™ Technology is used to monitor fan performance. If a fan reliability issue is detected, TC646 will trigger an alarm through the fault pin. ###Features Temperature Proportional Fan Speed, Suitable for Acoustic Control and Extended Fan Life Efficient PWM Fan Driver 3.0V to 5.5V Power Range: - Fan Voltage Independent of TC646 Power Supply Voltage, Supports Any Fan Voltage FanSense ™ Fault detection circuit shutdown mode supports NTC/PTC thermistor over temperature indication # # # Motor controller and driver, Microchip
