NAME
FUNCTION
12
VCC
Supply Voltage Input, +3V to +3.6V. Bypass to GND with a 0.1µF capacitor. A
47
Ω series resistor is recommended but not required for additional noise
filtering. See Typical Operating Circuit.

3
DXP1
Combined Remote-Diode Current Source and A/D Positive Input for Remote-
Diode Channel 1. DO NOT LEAVE DXP1 FLOATING; connect DXP1 to DXN if no
remote diode is used. Place a 2200pF capacitor between DXP1 and DXN for
noise filtering.
34
DXN
Combined Remote-Diode Current Sink and A/D Negative Input. DXN is internally
biased to one diode drop above ground.
4
5
DXP2
Combined Remote-Diode Current Source and A/D Positive Input for Remote-
Diode Channel 2. DO NOT LEAVE DXP2 FLOATING; connect DXP2 to DXN if no
remote diode is used. Place a 2200pF capacitor between DXP2 and DXN for
noise filtering.
510
OT1
Overtemperature Active-Low Output, Open Drain. OT1 is asserted low only when
the temperature is above the programmed OT1 threshold.
6
8
GND
Ground
7
9
SMBCLK
SMBus Serial-Clock Input
811
ALERT
SMBus Alert (Interrupt) Active-Low Output, Open-Drain. Asserts when
temperature exceeds user-set limits (high or low temperature) or when a remote
sensor opens. Stays asserted until acknowledged by either reading the status
register or by successfully responding to an alert response address. See the
ALERT Interrupts section.
9
12
SMBDATA
SMBus Serial-Data Input/Output, Open Drain
10
13
OT2
Overtemperature Active-Low Output, Open Drain. OT2 is asserted low only when
temperature is above the programmed OT2 threshold.
1, 16
N.C.
No Connect
6
ADD1
SMBus Slave Address Select Input (Table 10). ADD0 and ADD1 are sampled
upon power-up.
7
RESET
Reset Input. Drive RESET high to set all registers to their default values (POR
state). Pull RESET low for normal operation.
14
ADD0
SMBus Slave Address Select Input (Table 10). ADD0 and ADD1 are sampled
upon power-up.
—15
STBY
Hardware Standby Input. Pull STBY low to put the device into standby mode.
All registers’ data are maintained.
