描述

The DIO76087 is a load switch to provide up to 7 A load protection covering 0.5 V to 5.5 V voltage range,it could provide an integrated solution to monitor the output current to eliminate the need for an external current sense device. The DIO76087 provides a constant current limit that can be programmed by an external resistor. Once the device reaches its current limit threshold, the internal circuit regulates the gate voltage to hold the current in the power FET constant. The response time and the output current may have a small overshoot during this period. A capacitor connected to the SS pin determines the soft start time, with the soft start function, the DIO76087 can avoid inrush current during circuit start up. The DIO76087 supports a small RDS(ON) in tiny package QFN-12 (2 mm × 2 mm), it could provide a highly efficient and space-saving solution for such as notebook, tablet, optical module or other applications.
