The LM81CIMT-3 from Texas Instruments is a highly integrated data acquisition system for hardware monitoring in microprocessor-based systems like servers and PCs. It can monitor power supply voltages, temperatures, and fan speeds, with actual values readable at any time.
Key features include temperature sensing with an accuracy of ±3°C over a -40°C to 125°C range, and six positive voltage inputs for monitoring supplies like +5V, +12V, and +3.3V. It provides an 8-bit DAC output for fan speed control and includes two fan speed monitoring inputs. The device supports SMBus 1.0/1.1 serial interface compatibility.
This IC is housed in a 24-TSSOP package suitable for surface mounting. It operates within a supply voltage range of 2.8V to 3.8V and consumes a typical supply current of 0.4 mA. The LM81CIMT-3 also features a programmable WATCHDOG timer and a maskable interrupt system for critical alerts.
