Diodes AP2176 User Manual

AP2166/ AP2176
Description
The AP2166 and AP2176 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
Dual USB port power switches  Over-current and thermal protection  1.5A accurate current limiting  Reverse Current Blocking  90m 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: 6KV HBM, 300V MM  Active low (AP2166) or active high (AP2176) enable  Ambient temperature range -40°C to +85°C  SO-8 and MSOP-8EP (Exposed Pad): Available in “Green”
