NC

Not connected.

2

Vcc

Supply Voltage Input, 4.5V to 5.5V. Bypass to GND with a 0.1µF capacitor.

3

DXP1

Combined Current Source and A/D Positive Input for remote-diode channel 1. Do not leave DXP1 floating;

tie DXP1 to DXN if no remote diode on channel 1 is used. Place a 2200pF capacitor between DXP1 and

DXN for noise filtering.

4

DXN

Combined Current Sink and A/D Negative Input. DXN is common negative node of both remote diodes on

channel 1 and 2. The traces of DXP1-DXN and DXP2-DXN pairs should be routed independently. The

common DXN should be connected together as close as possible to the IC. DXN is internally connected to

the GND pin for signal ground use.

5

DXP2

Combined Current Source and A/D Positive Input for remote-diode channel 2. Do not leave DXP2 floating;

tie DXP2 to DXN if no remote diode on channel 2 is used. Place a 2200pF capacitor between DXP2 and

DXN for noise filtering.

SMBus Serial-Clock Input.

16

TH_SHUT

Thermal Shutdown Output, push-pull output.
