DESCRIPTION

The SP6ꢀ9 is a low Rds(on) high current switch designed with precision current lim-

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 operates from an input voltage range of 2.5V to 7V, making it ideal

for 3V and 5V applications. The SP6ꢀ9 is also protected from thermal overload

which limits power dissipation. In shutdown mode, the supply current drops to 2µA.
