DESCRIPTION

FEATURES

APPLICATIONS

SP619

High Current Power Switch

• Overcurrent deactivation 800mA

• Max leakage current less than 2µA

while deactivated

• Small 6 pin SOT-23 package

• Built-in Over-temperature Protection

• 4.5V to 5.5V input voltage range

• Ultra low cost handsets

• PDA, DSC, MP3 players

• Cell phones

• Power Distribution Switch

• Battery-Charger Circuit

iting to protect connected devices from damage due to a short circuit condition or

against current surges that may cause the supply voltages to fall out of regula-

tion. This switch is functional over an input voltage range of 2.5V to 7V, but is targeted

at 5V applications.

The SP619 is also protected from thermal overload which

limits power dissipation.
