Notes:

1. Absolute maximum ratings are limits beyond which

operation may cause permanent damage to the device.

These are stress ratings only; functional operation at or

above these limits is not implied.

2. When the input voltage (VIN) at any pin exceeds the

power supplies (VIN < GND or VIN > VDD), the current at

that pin should be limited to 5mA. The 20mA maximum

package input current rating limits the number of pins

that can safely exceed the power supplies with an input

current of 5mA to four. Parasitic components and/or

ESD protection circuitry are present on the aSC7611

pins. Care should be taken not to forward bias the

parasitic diode present on pins D+ and D-. Doing so by

more than 50mV may corrupt temperature

measurements.

Name and Function/Connection

Fan speed control 1. When in XOR tree test mode,

functions as XOR Tree output.

Fan speed control 2.

Fan speed control 3. Pull to ground at power on to enable

Address Select Mode (Address Select pin controls SMBus

address of the device).
