Datasheet Summary
Precision Load Switch with Adjustable Current Limit
DESCRIPTION
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, ranges from 75mA to 1.7A. Switch control is by a logic input (EN) capable of interfacing directly with low voltage control signals. Current is prevented from flowing when the switch is off and the output voltage is higher than the input voltage. BL2553 also Features thermal shutdown protection which shuts off the...
