LM96080 System Hardware Monitor with 2-Wire Serial Interface

Check for Samples: LM96080

FEATURES

DESCRIPTION

LM96080, compatible to LM80, is a hardware monitor

that contains a 10-bit delta-sigma ADC capable of

measuring 7 positive voltages and local temperature.

The LM96080 also measures the speed of two fans

and includes other hardware monitoring on an I²C®

interface. The LM96080 includes a sequencer that

performs WATCHDOG window comparisons of all

measured values and its interrupt outputs become

active when any values exceed the programmed

limits.

•

Local Temperature Sensing

7 Positive Voltage Inputs with 10-bit

Resolution

•

2 Programmable Fan Speed Monitoring Inputs

2.5 mV LSb and 2.56V Input Range

Chassis Intrusion Detector Input

WATCHDOG Comparison of All Monitored

Values

•

Separate Input to Show Status in Interrupt

Status Register of Additional External

Temperature Sensors Such as the LM26/27,

LM56/57, LM73, or LM75

I²C Serial Bus Interface Compatibility,

Supports Standard Mode, 100 kbits/s, and Fast

Mode, 400 kbits/s

The LM96080 is especially suited to interface to both

linear and digital temperature sensors. The 2.5 mV

LSb (least significant bit) and 2.56 volt input range is

ideal for accepting inputs from a linear sensor such

as the LM94022. The BTI is used as an input from

either digital or thermostat sensors such as LM73,

LM75, LM56, LM57, LM26, LM27, LM26LV, or other

LM96080.

•

Shutdown Mode to Minimize Power

Consumption

The LM96080 supports Standard Mode (Sm, 100

kbits/s) and Fast Mode (Fm, 400 kbits/s) I²C interface

modes of operation. LM96080 includes an analog

filter on the I²C digital control lines that allows

improved noise immunity and supports TIMEOUT

reset function on SDA and SCL that prevents I²C bus

lockup. Three I²C device address pins allow up to 8

parts on a single bus.

Programmable RST_OUT/OS Pin: RST_OUT

Provides a Reset Output; OS Provides an

Interrupt Output Activated by an

Overtemperature Shutdown Event

•

Software and Pin Compatible with the LM80

APPLICATIONS

The LM96080's 3.0V to 5.5V supply voltage range,

low supply current, and I²C interface make it ideal for

a wide range of applications. Operation is ensured
