Hardware Monitor With Thermal Diode Inputs And Sensorpath?⠂us - National Semiconductor

The LM41 is a hardware monitor that measures 2 tempera- ture zones, 5 voltages and has a single-wire Interface com- patible with National Semiconductors SensorPath bus. Sen- sorPath data is pulse width encoded, thereby allowing the LM41 to be easily connected to many general purpose micro-controllers. Several National Semiconductor Super I/O products include a fully integrated SensorPath master, that when connected to the LM41 CAN realize a hardware monitor function that includes limit checking for measured values, autonomous fan speed control and many other functions. The LM41 measures the temperature of its own die as well as one external device such as a processor thermal Diode or a Diode connected Transistor The LM41 CAN resolve tem- peratures up to 255C and down to -256C. The operating temperature range of the LM41 is 0C to +125C. Using ADC it measures +1.2V, +2.5V, +3.3V, +5V and +12V Analog input voltages with internal scaling resistors. The address programming pin allows two LM41s to be placed on one SensorPath bus. By National Semiconductor Corporation
