The LM85BIM is a high-performance product from Texas Instruments, a renowned global semiconductor company that designs, manufactures, and sells analog and embedded processing chips. This product is a sensor that is designed to monitor and control the temperature and fan speed in servers, workstations, and other computer systems. Its main function is to ensure that the system does not overheat, thereby preventing potential damage and ensuring optimal performance.

• Key Features:
• Monitors the temperature of up to four different zones including ambient temperature, processor temperature, and graphics card temperature
• Controls the speed of up to four fans based on temperature readings, adjusting PWM duty cycle
• Includes an analog-to-digital converter (ADC), digital-to-analog converter (DAC), and SMBus interface
• Programmable digital filter for reducing noise and improving temperature reading accuracy
• Wide operating temperature range of -40°C to 125°C
• Voltage supply range of 3.3V or 5V
