USB 2.0 HUB chip MA8601
MA8601 is a high-performance USB 2.0 high-speed 4-port USB HUB hub controller. The four port functions can work simultaneously and have low power consumption. Using MA8601 USB HUB is not only low cost, but users can also realize multiple hub configurations through EEPROM. options.
The chip adopts the mainstream SSOP28 package, can handle the functions of 4 USB ports at the same time, and has low power consumption. In addition, MA8601 also integrates a fast 8051 microprocessor and 1.5k pull-up resistors for upstream and downstream to achieve independent upstream and downstream channels. It also supports USB battery charging specification BC1.2 and realizes self-power supply by integrating a 5V to 3.3V/1.2V regulator.
