Combined Current Source and A/D Positive Input for Channel 1 Remote Transistor.
Connect to the emitter of a low beta transistor. Leave unconnected or connect to V
no remote transistor is used. Place a 100pF capacitor between DXP1 and DXN1 for
noise filtering.
Base Input for Channel 1 Remote Diode. Connect to the base of a pnp temperature-
sensing transistor.
Combined Current Source and A/D Positive Input for Channel 2 Remote Diode. Connect
to the anode of a remote-diode-connected temperature-sensing transistor. Leave
unconnected or connect to V
between DXP2 and DXN2 for noise filtering.
Cathode Input for Channel 2 Remote Diode. Connect the cathode of the channel 2
remote-diode-connected transistor to DXN2.
Combined Current Source and A/D Positive Input for Channel 3 Remote Diode. Connect
to the anode of a remote-diode-connected temperature-sensing transistor. Leave
unconnected or connect to V
between DXP3 and DXN3 for noise filtering.
Cathode Input for Channel 3 Remote Diode. Connect the cathode of the channel 3
remote-diode-connected transistor to DXN3.
Combined Current Source and A/D Positive Input for Channel 4 Remote Diode. Connect
to the anode of a remote-diode-connected temperature-sensing transistor. Leave
unconnected or connect to V
between DXP4 and DXN4 for noise filtering.
Cathode Input for Channel 4 Remote Diode. Connect the cathode of the channel 4
remote-diode-connected transistor to DXN4.
Active-Low Standby Input. Drive STBY low to place the MAX6694 in standby mode, or
high for operate mode. Temperature and threshold data are retained in standby mode.
No Connection. Must be connected to ground.
Overtemperature Active-Low, Open-Drain Output. OVERT asserts low when the
temperature of channels 1 and 4 exceeds the programmed threshold limit.
Supply Voltage Input. Bypass to GND with a 0.1µF capacitor.
SMBus Alert (Interrupt), Active-Low, Open-Drain Output. ALERT asserts low when the
temperature of any channel exceeds the programmed ALERT threshold.
SMBus Serial Data Input/Output. Connect to a pullup resistor.
SMBus Serial Clock Input. Connect to a pullup resistor.
Ground
Exposed Pad. Connect to a large ground plane to maximize thermal performance. Not
intended as an electrical connection point. (TQFN package only).
