MP62340/MP62341
3.3V/5V, Dual-Channel 1A
Current-Limited Power Distribution Switches
The Future of Analog IC Technology
DESCRIPTION FEATURES
1A Continuous Current
The MP62340/MP62341 Power Distribution
Accurate Current Limit
Switch features internal current limiting to
prevent damage to host devices due to faulty 2.7V to 5.5V Supply Range
load conditions. The MP62340/MP62341 140 A Quiescent Current
analog switch has 80m on-resistance and
80m MOSFET
operates from 2.7V to 5.5V input. It is available
Thermal-Shutdown Protection
with guaranteed current limits, making it ideal
Under-Voltage Lockout
for load switching applications. The
8ms FLAG Deglitch Time
MP62340/MP62341 has built-in protection for
No FLAG Glitch During Power Up
both over current and increased thermal stress.
Reverse Current Blocking
For over current, the device will limit the current
Active High & Active Low Options
by changing to a constant current mode.
Available is MSOP8E and SOIC8
As the temperature increases as a result of
UL ApprovedE322138
short circuit, then the device will shut off. The
APPLICATIONS
device will recover once the device temperature
PDAs
reduces to approx 120 C.
Portable GPS
The MP62340/MP62341 is available in 8-pin
Notebook PC
MSOP package with exposed pad and SOIC
Set-top-box
package without exposed pad.
Telecom and Network Systems
PC Card Hot Swap
