General Description
The MIC94066-69 are dual high-side load switches designed for operation between 1.7V to 5.5V. The devices contain a pair of low on-resistance, 115mΩ(max) P-channel MOSFETs that support over 2A of continuous current. The MIC94067 and MIC94069 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state.
