MIC94064/5
High Side Power Switches
General Description
Features
The MIC94064 and MIC94065 are high-side load
switches designed for operation between 1.7V to 5.5V.
The devices contain a low on-resistance P-channel
MOSFET that supports over 2A of continuous current.
• 1.7V to 5.5V input voltage range
• 2A continuous operating current
• 77mΩ (typ) RDSON
• Built-in level shift for control logic; can be operated by
The MIC94064/5 provides a slew rate controlled Soft-
Start turn-on of 115µs (typical) to prevent in-rush current
from glitching supply rails.
1.5V logic.
• Low 2µA quiescent current
• Soft-Start: 115µs
The MIC94065 features an active load discharge circuit
which insures capacitive loads retain no charge when
the main switch is in an OFF state.
• Micro-power shutdown <1µA
• Load discharge circuit: MIC94065
• Space saving 1.2x1.6 mm Thin MLF® package
An active pull-down on the enable input keeps
MIC94064/5 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.
Applications
• Load switch in portable applications:
-
-
-
-
-
Cellular phones
PDAs
MP3 players
Digital Cameras
Portable instrumentation
The MIC94064/5’s 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 <1µA maximize battery life.
• Battery switch-over circuits
• Level translator
