0.5A to 2.0A High-side Power Distribution Switches AP2822 General Description Features The AP2822 is an integrated high-side power switch Low MOSFET On Resistance: 85m that consists of N-Channel MOSFET, charge pump, Compliant to USB Specifications over current & temperature and other related protection Available 4 Versions of Continuous Load: circuits. The switchs low R , 85m, is designed 0.5A/1.0A/1.5A/2.0A DS(ON) to meet USB voltage drop requirements. The IC Logic Level Enable Pin: Available with includes soft-start to limit inrush current, over-current Active-high or Active-low Version protection, load short protection with fold-back, and Operating Voltage Range: 2.7V to 5.5V thermal shutdown to avoid switch failure during hot Low Supply Current: 68A (Typ.) plug-in. Under voltage lockout (UVLO) function is Low Shutdown Current: 1.0A (Max) used to ensure the device remain off unless there is a Under-voltage Lockout valid input voltage present. A FLAG output is Soft Start-up available to indicate fault conditions to the local USB Over-current Protection controller. Over Temperature Protection Load Short Protection with Fold-back The AP2822 is available in the standard package of No Reverse Current When Power Off SOT-23-5.
