AP2146

AP2146/AP2156 0.5A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH Features • • • • • • • • • • • • • • • • Dual USB port power switches Over-current and thermal protection 0.8A accurate current limiting Reverse Current Blocking 90mΩ 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, 300V MM Active high (AP2146) or active low (AP2156) enable Ambient temperature range -40ºC to 85°C SOP-8L and MSOP-8L-EP (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 Description The AP2146 and AP2156 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 SOP-8L and MSOP-8L-EP packages.
