GENERAL DESCRIPTION
The MON35W42 is an enhanced version of the MON35W41 hardware status monitoring IC. The MON35W42 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 the stability and proper operation of high-end computer systems. MON35W42 provides both ISA and I2C serial bus interface.
