ADT7462

Flexible Temperature,

Voltage Monitor, and

System Fan Controller

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.

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. Up to eight TACH inputs 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.

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

The ADT7462 also includes a THERM I/O and a RESET I/O.

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

pins are multi−functional. Five easy configuration options can be set

up using the easy configuration register. Users choose the

configuration closest to their requirements; individual pins can be

reconfigured after the easy configuration option has been chosen.
