W83781D Description

PRELIMINARY The W83781D is a hardware status monitoring IC for personal puters, server puters, or microprocessor based systems. W83781D can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end puter system to work stable and properly. W83781D provides both ISA and I2CTM serial bus interface.
