Notes:
• The maximum LED current supported is 25 mA.
• There should be a current limiting resistor on each LED output.
• The maximum off voltage on the transistor collector must not exceed 5.5V.
• The maximum on voltage for the transistor is 0.4V.
• The same circuit configuration as shown in
• The library-controlled or Beacon LED is driven by the AMI_LED_OUT signal.
