一,产品概述(General Description) ![]() The JTM9708 is an integrated 200mΩ power switch for self-powered and bus-powered Universal Series Bus (USB) applications. Its low quiescent supply current (50μA) and small package (SOT-23-5) is particularly suitable in battery-powered portable equipment. Several protection functions include soft start to limit inrush current during plug-in, current limiting at 0.8A(VIN=3.0V) and thermal shutdown to protect damage under over current conditions 二.产品特点(Features) ![]() 200mΩ Typ.
