Pin Description

PIN NAME FUNCTION

1, 5, 9, 13, 16 N.C. No Connection. Not internally connected. May be used for PC board trace routing.

Supply Voltage Input. +3.0V to +5.5V. Bypass to GND with a 0.1µF capacitor. A 200Ω series

resistor is recommended but not required for additional noise filtering.

3 DXP

Combined Current Source and ADC Positive Input for Remote-Junction Channel. If a remote-

sensing junction is not used, connect DXP to DXN.

4 DXN

Combined Current Sink and ADC Negative Input. DXN is internally biased to a diode voltage above

ground.

6 ADD1 SMBus Slave Address Select Input. ADD0 and ADD1 are sampled upon power-up.

7, 8 GND Ground

10 ADD0 SMBus Slave Address Select Input. ADD0 and ADD1 are sampled upon power-up.

11 ALERT SMBus Alert (Interrupt) Output. Open drain.

12 SMBDATA SMBus Serial-Data Input/Output. Open drain.

14 SMBCLK SMBus Serial-Clock Input

15 STBY

Hardware Standby Input. Temperature and comparison threshold data are retained in standby

mode. Low = standby mode, high = operating mode.
