JWQ7101 Single Power Switch with Flag DESCRIPTION FEATURES ®  AEC-Q100 qualified The JW Q7101 is a single channel current-limited power switch optimized for Universal Serial Bus  Up to 1.5A maximum load current (USB) and other hot-swap applications. The rise  ±11.8% accurate current limit@1.7A and fall times are controlled to minimize current  FLG: active low overshoot or undershoot during switches on/off.  Adjustable current limit  Reverse current blocking during shutdown The device has fast short-circuited response time and reverse current limit during enable for improved overall system robustness. It  Constant-current during over-current provides a complete protection solution, such as  Fast short-circuit response time: 2μs (typ.) reverse current blocking and limit, over-current  Adjustable current limit protection, over-temperature protection and  Operating range: 2.7V – 5.5V short-circuit protection, as well as controlled rise  Over-current protection, short-circuit time and under-voltage lockout function. A 7.5ms protection and thermal protection de-glitch time on the open-drain flag o
