OPEN-DRAIN OUTPUTS
The SMBDAT, ALERT, TCRIT and PWM outputs are open-drain outputs and do not have internal pull-ups. A
“High” level will not be observed on these pins until pull-up current is provided by an internal source, typically
through a pull-up resistor. Choice of resistor value depends on several factors but, in general, the value should
be as high as possible consistent with reliable operation. This will lower the power dissipation of the LM96163
and avoid temperature errors caused by self-heating of the device. The maximum value of the pull-up resistor to
provide the 2.1 V high level is 88.7 kΩ.
DIODE FAULT DETECTION
The LM96163 is equipped with operational circuitry designed to detect remote diode fault conditions:
• D+ shorted to V
DD
• D+ open or floating
• D+ shorted to GND.
