MIC94060/61/62/63
High Side Power Switches
General Description
Features
The MIC94060-63 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. The MIC94061 and
MIC94063 features an active load discharge circuit
which insures capacitive loads retain no charge when
the main switch is in an OFF state.
• 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
1.5V logic.
• Low 2µA quiescent current
• Soft-Start: MIC94062-63
• Micro-power shutdown <1µA
• Load discharge circuit: MIC94061, MIC94063
• Space saving 1.2mm x 1.6mm Thin MLF® package
MIC94060-61 feature rapid turn on while MIC94062-63
provide a slew rate controlled Soft-Start turn-on of 800µs
(typical) to prevent in-rush current from glitching supply
rails.
An active pull-down on the enable input keeps
MIC94060-63 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
MIC94060-63’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
