STCC5011, STCC5021

USB charging controller with integrated power switch and attach

detector

Datasheet - production data

Applications

• USB ports/hubs

• Personal computers, all-in-one PCs

• Monitors

• Notebooks, ultrabooks

VFQFPN 16L - 3 x 3 x 0.8 mm

• Tablet PCs

• Universal wall charging adapters

Features

Description

• Compliant with USB charging specifications

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.

BC1.2, USB 2.0 and USB 3.0 standards

• Compliant with Chinese telecommunications

industry standard YD/T 1591-2009

• Compatible with proprietary charging mode

(Apple 1 A / 2 A, BlackBerry , Korean tablets)

• Wide bandwidth, low-loss USB 2.0 data switch

• Integrated V

65 mΩ

power switch with low R of

BUS

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.

• Constant current mode overcurrent protection

• Soft-start to limit inrush current

• Adjustable current limit up to 2.8 A

• Short-circuit, thermal and undervoltage

This device also asserts the CHARGING/ATTACH

protection

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.

• Reverse voltage and reverse current protection

• Deglitched fault reporting output

• Supports remote wakeup in S3

• Charging indication output in DCP and CDP

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.

modes

• 3-hour safety counter for charging in S5

• Device attachment detection in G3 state

• Available in VFQFPN 16L

3 x 3 x 0.8 mm package with exposed pad

These two features permit the host system to

reduce consumption while no device is attached

or when there is no charging.

• Temperature range: -40 up to 85 °C

• UL and CB recognized components

(UL file number: E354278)
