Description
The STCC5011/STCC5021 device integrates, in
one package, a USB charger controller, a wide
bandwidth data switch and a high current power
switch. The device emulates several profiles
compatible with the USB battery charging
standard BC1.2, Chinese telecommunications
standard YD/T 1591-2009 and proprietary
charger modes.
The device can detect peripheral device
attachment when the host is in S4/S5 deep
sleep/off states or in G3 shutdown state. It asserts
the CHARGING/ATTACH output after the attach
event, allowing the host to turn on the high power
DC-DC converter and start charging.
This device also asserts the CHARGING/ATTACH
output in DCP modes if the charging current is
above the threshold. In CDP mode, it asserts the
CHARGING/ATTACH output after the CDP
negotiation if the charging current is above the
threshold.
After the current drops below the threshold, the
output is deasserted. This allows the host to turn
off the high power DC-DC converter and reduce
overall consumption in S4/S5 or in G3 states
which is critical when the host is battery-supplied.
These two features permit the host system to
reduce consumption while no device is attached
or when there is no charging.
