BL2553 Datasheet (BELLING) - Precision Load Switch

BL2553, Precision Load Switch

The BL2553 is a load switch which provides full protection to systems and loads which may encounter large current conditions.

BL2553 offers a 95mΩ current-limited switch which can operate over an input voltage range of 2.5-5.5V.

The current limit can be externally programmed by a precision resistor,

BL2553 Features

* thermal shutdown protection which shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating. When the switch current reaches the current limit, the parts operate in a constant-current mode to prohibit excessive currents from causing damage.
