AP2181A/ AP2191A 1.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description The AP2181A and AP2191A are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. This family of devices complies with USB 2.0 and is available with both polarities of Enable input. The AP2181A and AP2191A offer current and thermal limiting and short circuit protection as well as controlled rise time and undervoltage 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, MSOP-8EP, SOT25 and U-DFN2018-6 packages. Features  Single USB Port Power Switches  Over-Current and Thermal Protection  2.1A Accurate Current Limiting  Reverse Current Blocking  95mΩ On-Resistance  Input Voltage Range: 2.7V – 5.5V  0.6ms Typical Rise Time  Very Low Shutdown Current: 1µA (max)  Fault Report (FLG) with Blanking Time (7ms typ)  ESD Protection: 4kV HBM, 300V MM  Active Low (AP2181A) or Active High (AP2191A) Enable  Ambient Temperature Range: -40°C to +85°C  SOT25, SO-8, MSOP-8EP (Exposed Pad), and U-DFN2018-6: Available in “Green” Molding Compound (No Br, Sb)  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3)  UL Recognized, File Number E322375  IEC60950-1 CB Scheme Certified Applications  Consumer Electronics – LCD TV & Monitor, Game Machines  Communications – Set-Top Box, GPS, Smartphone  Computing – Laptop, Desktop, Servers, Printers, Docking Station, HUB Pin Assignments GND 1 ( Top View ) 8 NC IN 2 7 OUT IN 3 6 OUT EN 4 SO-8 5 FLG GND IN IN EN 1 2 3 4 ( Top View ) 8 NC 7 OUT 6 OUT 5 FLG MSOP-8EP ( Top View ) OUT 1 GND 2 FLG 3 5 IN 4 EN SOT25 ( Top View ) GND 1 6 OUT IN 2 5 OUT EN 3 4 FLG U-DFN2018-6 Notes: 1.
