MIC94073YC6 TR

The MIC94073YC6 TR is a high-side Power Switch designed for operation between 1.7 to 5.5V. The device contain a low on-resistance P-channel MOSFET that supports 1.2A of continuous current. The MIC94073 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an OFF state. An active pull-down on the enable input keeps MIC94073 in a default OFF state until the EN pin is pulled to a high level. Built-in level shift circuitry allows low voltage logic signals to switch higher supply voltages, or vice versa; high level logic signals can control low level voltages. MIC94073 operating voltage range makes them suitable for 1-cell Lithium ion and 2- to 3-cell NiMH/NiCad/Alkaline powered systems, as well as all 5V applications. Their low operating current of 2µA and low shutdown current of <lt/>1µA maximize battery life.

• 3A pulse current
• 120mΩ R DSON (typical)
• Built-in level shift for control logic, can be operated by 1.5V logic
• Low 2µA quiescent current
• Micro-power shutdown <lt/>1µA
