LM41 - Hardware Monitor with Thermal Diode Inputs and SensorPath Bus

General Description

The LM41 is a hardware monitor that measures 2 temperature zones, 5 voltages and has a single-wire interface compatible with National Semiconductor’s SensorPath bus.

SensorPath data is pulse width encoded, thereby allowing the LM41 to be easily connected to many general purpose micro-controllers.

Key Features

  • n SensorPath Interface.
  • 2 hardware programmable addresses n Voltage Monitoring.
  • 9-bit Σ∆ ADC Typical.

LM41 Hardware Monitor with Thermal Diode Inputs and SensorPath™ Bus May 2004 LM41 Hardware Monitor with Thermal Diode Inputs and SensorPath™ Bus General Description The LM41 is a hardware monitor that measures 2 temperature zones, 5 voltages and has a single-wire interface compatible with National Semiconductor’s SensorPath bus. SensorPath 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.
