AMC80 System Hardware Monitor with Two-Wire and SMBus Serial Interface Features 3 DescriptionThe AMC80isa system hardware monitoring and 10-Bit ADC With Seven Analog Inputs control circuit that includesa seven-channel, 10-bit• Fan-Speed Monitoring Inputs analog-to-digital converter (ADC), two programmable• Input Range/Resolution: fan-speed monitors, anda two-wire interface. The
AMC80 also includes programmable upper over-limit– Default: 2.56 V/2.5 mV and lower under-limit alarms that activate when the– Programmable: VDD/6 mV programmed limits are exceeded.• Chassis Intrusion Detection Input The AMC80 can interface with both linear and digital• Interrupt Alarms: temperature sensors. The 2.5-mV least significantbit– Upper Over-Limit (LSB) and 2.56-V input range can accept inputs from linear sensor such as the TMP20. The BTI pinis– Lower Under-Limit
used as an input froma digital sensor such as the• Interrupt Status Register Input for External TMP75. The AMC80 operates froma 3-Vto 5.5-VTemperature Sensors supply voltage, has low supply current, and can be• Shutdown Mode configured usinga two-wire interface, thus makingit
idealfora wide rangeof applications.• Programmable RST_OUT/OS Pin Compatible with LM96080 and LM80 The AMC80is availableina 24-lead TSSOP package
andis fully specified over the –40°C to +125°C• Package: 24-Pin TSSOP
