GENERAL DESCRIPTION

The ADP3629/ADP3630/ADP3631 are dual, high current, high speed drivers, capable of driving two independent N-channel power MOSFETs. The ADP3629/ADP3630/ADP3631 use the industry-standard footprint but add high speed switching performance and improved system reliability.

The ADP3629/ADP3630/ADP3631 have an internal temperature sensor and provide two levels of overtemperature protection: an overtemperature warning and an overtemperature shutdown at extreme junction temperatures.
