DESCRIPTION
The SP619 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 SP619 is also protected from thermal overload
which limits power dissipation. In shutdown mode, the supply current drops to 2µA.
