AP2145 Green 0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2145 is integrated high-side power switches optimized for (Top View) Universal Serial Bus (USB) and other hot-swap applications. The SO-8 family of devices complies with USB 2.0 and available with active low 1 8 EN OUT Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise time and under-voltage lockout FLG 2 7 IN functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. 3 6 OUT GND The AP2145 is available in SO-8 and MSOP-8EP packages. 4 5 NC NC (Top View) Features SO-8 Single USB Port Power Switches Over-Current and Thermal Protection (Top View) MSOP-8EP 0.8A Accurate Current Limiting Reverse Current Blocking EN 1 8 OUT 90m On-Resistance 7 2 FLG IN Input Voltage Range: 2.7V to 5.5V 6 OUT 3 0.6ms Typical Rise Time GND Very Low Shutdown Current: 1A (Max) 4 NC 5 NC Fault Report (FLG) with Blanking Time (7ms Typ) (Top View) ESD Protection: 6kV HBM, 400V MM MSOP-8EP Active Low (AP2145) Enable Ambient Temperature Range -40C to +85C SO-8 and MSOP-8EP (Exposed Pad): Available in Green Applications Molding Compound (No Br, Sb) Lead-Free Finish RoHS Compliant (Notes 1 & 2) Consumer Electronics LCD TV & Monitor, Game Machines Halogen and Antimony Free.

These are stress ratings only functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices. Note: 4.
