DESCRIPTION

1

Positive supply voltage. DC voltage from 3.0 V

to 5.5 V.

2

D+

Diode current source (anode).

3

D–

Diode sink current (cathode).

4

T_CRIT

T_CRIT alarm is open drain, active-LOW output

which requires an external pull-up resistor. It

functions as a system interrupt or power

shutdown.

5

GND

Power supply ground.

6

ALERT

ALERT alarm is an open drain, active-LOW

output which requires an external pull-up resistor.

It functions as an interrupt indicating that the

temperature of the on-chip or remote diode is

above or below programmed over temperature

or under temperature thresholds.

7

SDATA

an open drain output which requires an external

pull-up resistor.

8

SCLK

external pull-up resistor.

MAXIMUM RATINGS

All voltages are referenced to GND.

NOTES:

1. The D+ and D– pins are 1000 V HBM and 100 V MM due to the higher sensitivity of the analog pins that introduces a limitation to the circuit

protection structure.
