3 / 5 page Pin Descriptions (Continued) Label Pin # Function Typical Connection D4+ 3 Diode Current Source To fourth Diode Anode. Connected to remote discrete diode-connected transistor junction or to the diode-connected transistor junction on a remote IC whose die temperature is being sensed. A capacitor is not required between D4+ and D-. A 100 pF capacitor between D4+ and D- can be added and may improve perfomance in noisy systems. Float this pin if this thermal diode is not used. D3+ 4 Diode Current Source To third Diode Anode. Connected to remote discrete diode-connected transistor junction or to the diode-connected transistor junction on a remote IC whose die temperature is being sensed. A capacitor is not required between D3+ and D-. A 100 pF capacitor between D3+ and D- can be added and may improve perfomance in noisy systems. Float this pin if this thermal diode is not used. D− 5 Diode Return Current Sink To all Diode Cathodes. Common D- pin for all four remote diodes. D2+ 6 Diode Current Source To second Diode Anode. Connected to remote discrete diode-connected transistor junction or to the diode-connected transistor junction on a remote IC whose die temperature is being sensed. A capacitor is not required between D2+ and D-. A 100 pF capacitor between D2+ and D- can be added and may improve perfomance in noisy systems. Float this pin if this thermal diode is not used. D1+ 7 Diode Current Source To first Diode Anode. Connected to remote discrete diode-connected transistor junction or to the diode-connected transistor junction on a remote IC whose die temperature is being sensed. A capacitor is not required between D1+ and D-. A 100 pF capacitor between D1+ and D- can be added and may improve perfomance in noisy systems. Float this pin if this thermal diode is not used. GND 8 Power Supply Ground System low noise ground. A0 9 Dgital Input SMBus slave address select pin. Selects one of three addresses. Can be tied to V DD, GND, or to the middle of a resistor divider connected between V DD and GND. TCRIT1 10 Digital Output, Open-Drain Critical temperature output 1. Requires pull-up resistor. Active "LOW". TCRIT2 11 Digital Output, Open-Drain Critical temperature output 2. Requires pull-up resistor. Active "LOW". SMBDAT 12 SMBus Bi-Directional Data Line, Open-Drain Output From and to Controller; may require an external pull-up resistor SMBCLK 13 SMBus Clock Input From Controller; may require an external pull-up resistor TCRIT3 14 Digital Output, Open-Drain Critical temperature output 3. Requires pull-up resistor. Active "LOW". www.national.com 3 |
