Maxim Integrated Temperature Sensor, PWM Output, Surface Mount, SMBus, ±1°C, 16 Pins

MAX6639 Temperature Monitor ; PWM Fan Controller. The MAX6639 series temperature monitor ; PWM fan controller is designed to monitor internal temperature plus the temperature of an external diode-connected transistor or alternatively, monitor the temperature of 2 external diode-connected transistors. The fan control element of the MAX6639, uses temperature data to change the speed of up to 2 cooling fans. Applications include desktop and notebook computers, servers, projectors and networking equipment. Features; 2 PWM outputs 2 Thermal-Diode Inputs Temperature measurement up to 150°C
