High Current Power Switch

DESCRIPTION

The SP69 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 operates from an input voltage range of 2.5V to 7V, making it ideal for 3V and 5V applications. The SP69 is also protected from thermal overload which limits power dissipation. In shutdown mode, the supply current drops to 2µA.
