目录产品概述 返回TOP The CXAS42290 CXAS42290-1 CXAS42290-2 is a single channel current-limited power switch optimized for Universal Serial Bus (USB) and other hot-swap applications. The rise and fall times are controlled to minimize current overshoot or undershoot during switches on/off. The device has fast short-circuit response time for improved overall system robustness. It provides a complete protection solution, such as over-current protection, over-temperature protection and short-circuit protection, as well as controlled rise time and under-voltage lockout function. A7.5ms de-glitch time on the open-drain Flag output prevents false over-current reporting. CXAS42290 CXAS42290-1 CXAS42290-2 offers SOT23-5 package.产品特点 返回TOP 50mΩ Integrated N-MOSFET Switch Accurate Current Limit FLG: active low Constant-Current During Over-Current Fast Short-Circuit Response Time: 2μs (typ.)
