AP2162A/ AP2172A 1A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE Description Pin Assignments The AP2162A and AP2172A are dual channel current-limited ( Top View ) integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices 1 8 GND FLG1 complies with USB standards and available with both polarities of Enable input. 2 7 IN OUT1 The devices have fast short-circuit response time for improved overall 3 6 EN1 OUT2 system robustness, and have integrated output discharge function to ensure completely controlled discharging of the output voltage EN2 4 5 FLG2 capacitor. They provide a complete protection solution for application subject to heavy capacitive loads and the prospect of short circuit, SO-8 and offer reverse current blocking, over-current, over-temperature and short-circuit protection, as well as controlled rise time and under- ( Top View ) voltage lockout functionality. A 7ms deglitch capability on the open- drain flag output prevents false over-current reporting and does not 1 8 FLG1 GND require any external components. IN 2 7 OUT1 6 All devices are available in SO-8, MSOP-8EP and U-DFN3030-8 3 OUT2 EN1 packages. 4 5 EN2 FLG2 MSOP-8EP Features Dual Channel Current-Limited Power Switch with Output ( Top View ) Discharge Fast Short-Circuit Response Time: 2s 1 GND 8 FLG1 1.4A Accurate Current Limiting 2 7 IN OUT1 Reverse Current Blocking 85m On-Resistance 6 3 OUT2 EN1 Input Voltage Range: 2.7V - 5.5V 5 EN2 4 FLG2 Built-In Soft-Start with 0.6ms Typical Rise Time Short Circuit and Thermal Protection U-DFN3030-8 Fault Report (FLG) with Blanking Time (7ms typ) ESD protection: 2kV HBM, 300V MM Active High (AP2172A) or Active Low (AP2162A) Enable Ambient Temperature Range: -40C to +85C Applications SO-8, MSOP-8EP and DFN3030E-8 (Exposed Pad): Available LCD TVs & Monitors in Green Molding Compound (No Br, Sb) Set-Top-Boxes, Residential Gateways Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Laptops, Desktops, Servers, Halogen and Antimony Free.
