Flexible Temperature and Voltage Monitor

and System Fan Controller

ADT7462

FEATURES

GENERAL DESCRIPTION

One local and up to three remote temperature channels

Series resistance cancellation on remote channels

Thermal protection using THERM pins

The ADT7462 is a flexible systems monitor IC, suitable for use

in a wide variety of applications. It can monitor temperature in

up to three remote locations, as well as its ambient temperature.

Up to four PWM fan drive outputs

There are up to four PWM outputs. These can be used to control

the speed of a cooling fan by varying the % duty cycle of the

PWM drive signal applied to the fan. The ADT7462 supports

high frequency PWM for 4-wire fans and low frequency PWM

for 2-wire and 3-wire fans. There are up to eight TACH inputs,

which can be used to measure the speed of 3-wire and 4-wire

fans. There are up to 13 voltage monitoring inputs, ranging

from 12 V to 0.9 V.

Supports both high and low frequency PWM drives

Up to eight TACH inputs

Measures the speed of 3-wire and 4-wire fans

Automatic fan speed control loop

Includes dynamic T_MINcontrol

Monitors up to 13 voltage inputs

Monitors up to 7 VID inputs

Includes VID-on-fly support

Bidirectional reset

Chassis intrusion detect

SMBus 1.1- and SMBus 1.0-compatible

3.3 V and 5 V operation

Extended operating range from −40°C to +125°C

Space-saving 32-lead chip scale package

The ADT7462 is fully compatible with SMBus 1.1 and SMBus 1.0.

THERM

RESET

The ADT7462 also includes a

I/O and a

I/O.

The ADT7462 is available in a 32-lead LFCSP_VQ. Many of the

pins are multifunctional. There are five easy configuration options,

which are set up using the easy configuration register. Users pick

the configuration closest to their requirements; individual pins

can be reconfigured after the easy configuration option has

been chosen.
