Absolute Maximum Ratings

The following table lists the absolute maximum ratings for the PD69101. Exceeding these ratings can cause damage

to the device. Pin Port_Sense is ESD sensitive and passes 500V HBM. All voltages are with respect to ground.

Currents are marked positive when flowing into a specified terminal and marked negative when flowing out of a

specified terminal.
