AP2111

AP2101/AP2111 2A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Features • • • • • • • • • • • • • • • • • Single USB port power switches with auto-discharge Short-circuit current and thermal protection 2.45A accurate current limiting Fast transient response time: 5μs 90mΩ on-resistance Reverse Current Blocking 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 (AP2101) or active high (AP2111) enable Ambient temperature range: -35°C 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 (pending) IEC60950-1 CB Scheme Certified Description The AP2101 and AP2111 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, under-voltage lockout and auto-discharge functionalities. 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.
