ASPS6601
Power Distribution Switch
General Description
Features
The ASPS6601 is an integrated power switch for
self-powered and bus-powered Universal Serial Bus
(USB) application. The ASPS6601 has several
protections features such as current limiting and
thermal shutdown to prevent catastrophic switch
failure caused by increasing power dissipation when
continuous heavy loads or short circuit occurs. A
built-in P-channel MOSFET used for power MOS
has superior Ron and easy control characteristics.
The output reverse-current protection turns off the
MOSFET switch whenever occurs the unexpected
