AP2142A/AP2152A 0.5A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE Description The AP2142A and AP2152A are dual channel current-limited integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB standards and available with both polarities of Enable input. The devices have fast short-circuit response time for improved overall system robustness, and have integrated output discharge function to ensure completely controlled discharging of the output voltage capacitor. They provide a complete protection solution for application subject to heavy capacitive loads and the prospect of short circuit, and offer reverse current blocking, over-current, over-temperature 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 DFN3030E-8 packages. in SO-8, MSOP-8-EP and Pin Assignments ( Top View ) GND IN 1 2 8 7 6 5 FLG1 OUT1 OUT2 FLG2 EN1 3 EN2 4 N EW PRODUCT SO-8 ( Top View ) GND IN EN1 EN2 1 2 3 4 8 7 6 5 FLG1 OUT1 OUT2 FLG2 Features • • • • • • • • • • • • • • • • Dual channel current-limited power switch with output discharge Fast short-circuit response time: 2µs 0.7A accurate current limiting Reverse Current Blocking 85mΩ on-resistance Input voltage range: 2.7V – 5.5V Built-in soft-start with 0.6ms typical rise time Short circuit and thermal protection Fault report (FLG) with blanking time (7ms typ) ESD protection: 2KV HBM, 300V MM Active high (AP2152A) or active low (AP2142A) enable Ambient temperature range: -40ºC to 85°C SO-8, MSOP-8-EP and DFN3030E-8 (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 MSOP-8-EP ( Top View ) GND IN EN1 EN2 1 2 3 4 8 7 6 5 FLG1 OUT1 OUT2 FLG2 DFN3030E-8 Applications • • • • LCD TVs & Monitors Set-Top-Boxes, Residential Gateways Laptops, Desktops, Servers, Printers, Docking Stations, HUBs 1.
