SP619

SP619 High Current Power Switch FEATURES Max RDS(ON) .377 Ohms 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 APPLICATIONS Ultra low cost handsets PDA, DSC, MP3 players Cell phones Power Distribution Switch Battery-Charger Circuit 654 SP619 SOT23-6 123 DESCRIPTION The SP619 is a low RDS(ON) high current switch designed with precision current limiting 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 regulation. 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. In shutdown mode, the supply current drops to 2µA. Vin Vin SP619 TYPICAL APPLICATION CIRCUIT Vout Cin .1µF ON/...
