ADT7462

Function Description: Easy Configuration Options

There are a number of multifunctional pins on the

ADT7462 that need to be configured on powerup to suit the

desired application. Note that due to the large number of pins

that need to be configured, it could take several SMBus

transactions to achieve the required configuration. For this

reason, the ADT7462 has five easy configuration options.

The user sets a bit in the easy configuration option register

(0x14) to set up the required configuration (see Table 1).

Once the most convenient easy configuration option has

been set, the user can configure any of the pins individually.

The setup complete bit (Bit 5 of Register 0x01) must then be

set to 1 to indicate that the ADT7462 is configured correctly,

and then monitoring of the selected channels begins.

The following is a detailed description of the five easy

configuration options that are available.

Configuration Option 1

Configuration Option 1 is the default configuration. It is

also the most suitable for thermal monitoring, voltage

monitoring, and fan control for single and dual processor

systems. Features of Configuration Option 1 include the

following:

• One local and three remote temperature channels

• Four PWM drives and eight TACH inputs

• Two THERM I/Os

• Voltage monitoring

• +3.3V
