MM3691

MITSUMI USB connector temperature protection IC MM3691 Series USB connector temperature protection IC Monolithic IC MM3691 Series Outline Micro USB (µUSB) is one of the most popular charging connector for current portable devices. Due to exposed terminal and its small size, accident by contamination and/or damage may need to be considered as potential risk of the safety. Mitsumi MM3691 provides more secure charging function than conventional technology using just PTC/Fuse by detecting abnormal temperature. By considering abnormal voltage drop due to like internal contamination of the connector, MM3691 also has Over-discharge detection function to shutdown extra current. Features (Unless otherwise specified, Topr=+25°C) (1) TH pin detection voltage1 (VDD=5.0V) (2) TH pin detection dead time (3) Low voltage Detect 4.165V Typ. (0.833×VDD Typ.) 50ms Typ. 3.500V Typ. (4) Low voltage Detect Delay time (function for the pulse charge) is provided. 50ms Typ. (5) Reset detection Vo...
