SP619 - High Current Power Switch

General 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.

Key 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.
