The TC664/TC665 motor driver is a PWM fan speed controller designed for brushless DC fans, featuring FanSense technology for enhanced reliability. It operates within a supply voltage range of 3.0V to 5.5V and supports a maximum output current of 5mA. The device is housed in a compact 10-pin MSOP package and is suitable for applications such as personal computers, servers, and general-purpose fan speed control. This motor driver provides temperature proportional fan speed control, which helps reduce acoustic noise and prolongs fan life. It includes features such as over-temperature detection, fan fault detection, and a 2-wire SMBus-compatible interface for easy integration. The operating temperature range is -40¬8C to +85¬8C, making it suitable for various environmental conditions. The TC664/TC665 also supports low-power shutdown mode, consuming only 5¬µA in this state, which is beneficial for energy-efficient designs.
