1 / 13 page AP2145/AP2155 0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE AP2145/AP2155 Document number: DS32031 Rev. 2 - 2 1 of 13 www.diodes.com September 2010 © Diodes Incorporated Description The AP2145 and AP2155 are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. All devices are available in SO-8 and MSOP-8EP packages. Features • Single USB port power switches • Over-current and thermal protection • 0.8A accurate current limiting • Reverse Current Blocking • 90m Ω on-resistance • Input voltage range: 2.7V – 5.5V • 0.6ms typical rise time • Very low shutdown current: 1uA (max) • Fault report (FLG) with blanking time (7ms typ) • ESD protection: 6KV HBM, 400V MM • Active high (AP2155) or active low (AP2145) enable • Ambient temperature range -40ºC to 85°C • SO-8 and MSOP-8EP (Exposed Pad): Available in “Green” Molding Compound (No Br, Sb) • Lead Free Finish/ RoHS Compliant (Note 1) • UL Recognized, File Number E322375 • IEC60950-1 CB Scheme Certified Pin Assignments SO-8 1 2 3 4 8 7 6 5 OUT IN NC OUT EN NC GND FLG (Top View) MSOP-8EP 1 2 3 4 8 7 6 5 OUT IN NC OUT EN NC GND FLG (Top View) Applications • Consumer electronics – LCD TV & Monitor, Game Machines • Communications – Set-Top-Box, GPS, Smartphone • Computing – Laptop, Desktop, Servers, Printers, Docking Station, HUB Notes: 1.
