These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
A. When using the AutoTrack feature with the PTH08T225W, a 100-k Ω pull-up resistor to V
I
is required. If the AutoTrack
feature is not used, this pin must be directly connected to V
I
.
