The EUP3510 is a Current Limited P-channel MOSFET power switch designed for high-side load-switching applications. An integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of regulation. It can be used to control loads that require up to 1A. In order to fit different application, current limit threshold is programmed with a resistor from SET Pin to ground. The quiescent supply current is typically a low 8μA, making the device ideal for portable battery-operated equipment. In shutdown mode, the supply current decreases to less than 0.1μA.

Additional features include thermal shutdown to prevent catastrophic switch failure from high current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present.

The EUP3510 is available in a 5 pin SOT-23 package.
