–

Default: 2.56 V/2.5 mV

DESCRIPTION

Programmable: V_DD/6 mV

The AMC80 is a system hardware monitoring and

control circuit that includes a seven-channel, 10-bit

analog-to-digital converter (ADC), two programmable

fan-speed monitors, and a two-wire interface. The

AMC80 also includes programmable upper over-limit

and lower under-limit alarms that activate when the

programmed limits are exceeded.

Upper Over-Limit

Lower Under-Limit

•

Interrupt Status Register Input for External

Temperature Sensors

The AMC80 can interface with both linear and digital

temperature sensors. The 2.5-mV least significant bit

(LSB) and 2.56-V input range can accept inputs from

a linear sensor such as the TMP20. The BTI pin is

used as an input from a digital sensor such as the

TMP75. The AMC80 operates from a 3-V to 5.5-V

supply voltage, has low supply current, and can be

configured using a two-wire interface, thus making it

ideal for a wide range of applications.

•

Shutdown Mode

Programmable RST_OUT/OS

Pin Compatible with LM96080 and LM80

Package: 24-Pin TSSOP

APPLICATIONS

•

Communications Equipment

Servers

The AMC80 is available in a 24-lead TSSOP package

and is fully specified over the –40°C to +125°C

temperature range.
