  • Features

    · Single USB port power switches Over-current and thermal protection 1.5A accurate current limiting Reverse Current Blocking 120m on-resistance Input voltage range: 5.5V 0.6ms typical rise time Very low shutdown current: 1uA (max) Fault report (FLG) with blanking time (7ms typ) ESD protection: 4KV HBM, 400V MM Active low (AP2161) or active high (AP2171) enable Ambient temperature range SOT25, SOP-8L and MSOP-8L-EP (Exposed Pad): Available in "Green" Molding Compound (No Br, Sb) Lead Free Finish / RoHS Compliant (Note 1) UL pending, File E322375


    The AP2161 and AP2171 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 SOP-8L, MSOP-8L-EP and SOT25 packages
