Winbond Electronics Corp. is introducing a new, high-precision, energy-saving hardware monitoring IC seriesthe W83L771AWG/773G/775G.

These devices support advanced features such as user-programmable conversion rates for OEM-optimized designs, and low-power standby mode to minimize the power consumption by notebook PCs, desktop PCs and servers.

The W83L77x series products feature an on-die temperature sensor as standard. The W83L771AWG supports one remote temperature sensor (one local and one remote). The W83L773G and the W83775G support two remote temperature sensors (one local and two remote). The relevant temperature values from these sensors typically form the basis of system health management.

In addition to temperature monitoring, the W83L771AWG/775G devices allow users to set critical temperature limits. When the monitored temperature exceeds the limits, the devices will alert the user. Users can activate out-of-range temperature protection mechanisms as required, including shutting down the system to avoid possible damage. Noise filters are included for the remote temperature sensing channel to minimize noise interference on temperature measurement. The system interface of these devices is I?C bus. The W83L771AWG is available in both 8-pin TSSOP and SOP packages, the W83L773G is available in 8-pin TSSOP package and the W83L775G is available in 10-pin TSSOP package.
