Cathode Input for Channel 4 Remote Diode. Connect the cathode of the channel 4 remote-diode-
connected transistor to DXN4. If the channel 4 remote transistor is a substrate pnp (e.g., on a CPU
die), connect the base of the pnp to DXN4. Leave DXN4 unconnected or connect to DXP4 if a
remote diode is not used. Connect a 100pF capacitor between DXP4 and DXN4 for noise filtering.
Combined Current Source and ADC Positive Input for Channel 5 Remote Diode. Connect DXP5 to
the anode of a remote-diode-connected, temperature-sensing transistor. Leave DXP5 unconnected
or connect to DXN5 if a remote diode is not used. Connect a 100pF capacitor between DXP5 and
DXN5 for noise filtering.
Cathode Input for Channel 5 Remote Diode. Connect the cathode of the channel 5 remote-diode-
connected transistor to DXN5. If the channel 5 remote transistor is a substrate pnp (e.g., on a CPU
die), connect the base of the pnp to DXN5. Leave DXN5 unconnected or connect to DXP5 if a
remote diode is not used. Connect a 100pF capacitor between DXP5 and DXN5 for noise filtering.
Cathode Input for Channel 6 Remote Diode. Connect the cathode of the channel 6 remote-diode-
connected transistor to DXN6. If the channel 6 remote transistor is a substrate pnp (e.g., on a CPU
die), connect the base of the pnp to DXN6. Leave DXN6 unconnected or connect to DXP6 if a
remote diode is not used. Connect a 100pF capacitor between DXP6 and DXN6 for noise filtering.
Combined Current Source and ADC Positive Input for Channel 6 Remote Diode. Connect DXP6 to
the anode of a remote-diode-connected, temperature-sensing transistor. Leave DXP6 unconnected
or connect to DXN6 if a remote diode is not used. Connect a 100pF capacitor between DXP6 and
DXN6 for noise filtering.
Cathode Input for Channel 7 Remote Diode. Connect the cathode of the channel 7 remote-diode-
connected transistor to DXN7. If the channel 7 remote transistor is a substrate pnp (e.g., on a CPU
die), connect the base of the pnp to DXN7. Leave DXN7 unconnected or connect to DXP7 if a
remote diode is not used. Connect a 100pF capacitor between DXP7 and DXN7 for noise filtering.
Combined Current Source and ADC Positive Input for Channel 7 Remote Diode. Connect DXP7 to
the anode of a remote-diode-connected, temperature-sensing transistor. Leave DXP7 unconnected
or connect to DXN7 if a remote diode is not used. Place a 100pF capacitor between DXP7 and
DXN7 for noise filtering.
Active-Low Standby Input. Drive STBY logic-low to place the MAX6581 in standby mode, or logic-
high for normal mode. Temperature and threshold data are retained in standby mode.
Internally Connected. I.C. is internally connected to V
Overtemperature Active-Low, Open-Drain Output. OVERT asserts low when the temperature of any
remote channel exceeds the programmed threshold limit.
Supply Voltage Input. Bypass to GND with a 0.1FF capacitor.
SMBus Alert (Interrupt), Active-Low, Open-Drain Output. ALERT asserts low when the temperature of
any channel crosses a programmed ALERT high or low threshold.
SMBus Serial-Data Input/Output. Connect SMBDATA to a pullup resistor.
SMBus Serial-Clock Input. Connect SMBCLK to a pullup resistor.
