onsemi ADM1026
The ADM1026 is a complete system hardware monitor for microprocessor-based systems, providing measurement and limit comparison of various system parameters. The ADM1026 has up to 19 analog measurement channels. The ADM1026 can monitor two other power supply voltages by measuring its own VCC and the main system supply.ADM1026 Complete Thermal System Management Controller Fifteen analog voltage inputs are provided, five of which are dedicated to monitoring +3.3 V, +5.0 V, and 12 V power supplies, and the processor core voltage. One input (two pins) is dedicated to a remote temperature-sensing diode. Two additional pins can be configured as general-purpose analog inputs to measure 0 V to 2.5 V, or as a second temperature sensing input. The eight remaining inputs are general-purpose analog inputs with a range of 0 V to 2.5 V or 0 V to 3.0 V. The ADM1026 also has an on-chip temperature sensor. The ADM1026 has eight pins that can be configured for fan speed measurement or as general-pu
