STCC2540

USB charging controller with integrated power switch

Datasheet - production data

Applications

• USB ports / hubs

• Personal computers, all-in-one PCs

• Monitors

• Notebooks, ultrabooks

• Tablet PCs

VFQFPN 16L 3 x 3 x 0.8 mm

• Universal wall charging adapters

Description

Features

The STCC2540 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.

• Compliant with USB charging specifications

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

The device asserts the charging flag in DCP

modes if the charging current is higher than the

threshold. In CDP mode, it asserts the charging

flag after the CDP negotiation if the charging

current is higher than the threshold.

• Integrated V

65 mΩ

power switch with low R of

BUS

• Constant current mode overcurrent protection

• Soft-start to limit inrush current

After the current drops below the threshold, the

output is deasserted, allowing the host to turn off

the high power DC-DC converter and reduce

overall consumption in S4/S5 states, which is

critical when the host is battery supplied.

• Adjustable current limit up to 2.8 A

• Short-circuit, thermal and undervoltage

protection

• Reverse voltage and reverse current protection

• Deglitched fault reporting output

• Supports remote wakeup in S3

• Charging indication output in DCP and CDP

modes

• Package: VFQFPN 16L 3 x 3 x 0.8 mm with

exposed pad

• Temperature range: -40 up to 85 °C

• UL and CB recognized components

(UL file number: E354278)
