1 / 19 page  Preliminary Datasheet 0.5A to 2.0A High-side Power Distribution Switches AP2822 Dec. 2012 Rev 1. 1 BCD Semiconductor Manufacturing Limited 1 General Description The AP2822 is an integrated high-side power switch that consists of N-Channel MOSFET, charge pump, over current & temperature and other related protection circuits. The switch’s low RDS(ON), 85mΩ, is designed to meet USB voltage drop requirements. The IC includes soft-start to limit inrush current, over-current protection, load short protection with fold-back, and thermal shutdown to avoid switch failure during hot plug-in. Under voltage lockout (UVLO) function is used to ensure the device remain off unless there is a valid input voltage present. A FLAG output is available to indicate fault conditions to the local USB controller. The AP2822 is available in the standard package of SOT-23-5. Applications • USB Power Management • USB Bus/Self Powered Hubs • Hot-plug Power Supplies • Battery-charger Circuits • Notebooks, Motherboard PCs Features • Low MOSFET On Resistance: 85mΩ • Compliant to USB Specifications • Available 4 Versions of Continuous Load: 0.5A/1.0A/1.5A/2.0A • Logic Level Enable Pin: Available with Active-high or Active-low Version • Operating Voltage Range: 2.7V to 5.5V • Low Supply Current: 68µA (Typ.) • Low Shutdown Current: 1.0µA (Max) • Under-voltage Lockout • Soft Start-up • Over-current Protection • Over Temperature Protection • Load Short Protection with Fold-back • No Reverse Current When Power Off • Deglitched FLAG Output with Open Drain • With Output Shutdown Pull-low Resistor Figure 1.
