3 / 17 page Pin Description Label Pin # Function Typical Connection NC 1, 5 floating, unconnected Left floating. PC board traces may be routed through the pads for these pins. No restrictions applied. V CC 2 Positive Supply Voltage Input DC Voltage from 3.0 V to 3.6 V D+ 3 Diode Current Source To Diode Anode. Connected to remote discrete diode junction or to the diode junction on a remote IC whose die temperature is being sensed. When not used they should be left floating. D− 4 Diode Return Current Sink To Diode Cathode. Must float when not used. ADD0–ADD1 10, 6 User-Set SMBus (I 2C) Address Inputs Ground (Low, “0”), V CC (High, “1”) or open (“TRI-LEVEL”) GND 7, 8 Power Supply Ground Ground NC 9, 13, 15 Manufacturing test pins. Left floating. PC board traces may be routed through the pads for these pins, although the components that drive these traces should share the same supply as the LM82 so that the Absolute Maximum Rating, Voltage at Any Pin, is not violated. INT 11 Interrupt Output, open-drain Pull Up Resistor, Controller Interrupt or Alert Line SMBData 12 SMBus (I 2C) Serial Bi-Directional Data Line, open-drain output From and to Controller, Pull-Up Resistor SMBCLK 14 SMBus (I 2C) Clock Input From Controller, Pull-Up Resistor T_CRIT_A 16 Critical Temperature Alarm, open-drain output Pull Up Resistor, Controller Interrupt Line or System Shutdown www.national.com 3 |
