Sensylink Micro's first-level agent CTF2304 system level thermal management solution chip

Sensylink Microelectronics is a high-performance semiconductor design company specializing in sensor chips and mixed-signal chips. Since 2015, our company has successfully developed and mass-produced more than 500 competitive products with completely independent intellectual property rights. Our products are widely used in industrial, automotive, communications and consumer electronics markets. ,

The CTF2301A is a system-level thermal management solution chip that includes 1-channel local and 1-channel remote temperature sensors, and 1-channel fan speed monitor and controller. Temperature and fan speed data can be read directly through the SMBus/I2C interface. It is ideal for laptops, routers, telecommunications systems, etc.
