AP2401/AP2411 2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH LATCH-OFF Description The AP2401 and AP2411 are single 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 is 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 applications 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. AP2401 and AP2411 will be latched off after 7ms deglitch. All devices are available DFN3030-8 packages. in SO-8, MSOP-8EP and MSOP-8EP Pin Assignments (Top View) GND 1 IN 2 IN 3 EN 4 SO-8 8 7 6 5 NC OUT OUT FLG N EW PRODUCT (Top View) GND IN IN EN 1 2 3 4 8 7 6 5 NC OUT OUT FLG (Top View) Features GND 1 2 3 4 8 7 6 5 NC OUT OUT FLG • • • • • • • • • • • • • • • • • • Note: Single channel current-limited power switch Output discharge function Output current latch-off when OCP triggered Fast short-circuit response time: 2µs 2.5A accurate current limiting Reverse current blocking 70mΩ on-resistance Input voltage range: 2.7V – 5.5V Built-in soft-start with 0.6ms typical rise time Over-current and thermal protection Fault report (FLG) with blanking time (7ms typ) ESD protection: 4KV HBM, 300V MM Active low (AP2401) or active high (AP2411) enable Ambient temperature range: -40ºC to 85°C SO-8, MSOP-8EP and DFN3030-8: 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 IN IN EN DFN3030-8 Applications • • • • LCD TVs & Monitors Set-Top-Boxes, Residential Gateways Laptops, Desktops, Servers, e-Readers Printers, Docking Stations, HUBs 1.
