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.
