Programmable USB Port Power Controller with Charger Emulation

Datasheet

Revision 1.4 (07-16-13)

SMSC UCS1002

DATASHEET

The A_DET# pinprovides an active low open-drain output indication that a valid Attach Detection event

has occurred. It will remain asserted until the UCS1002 is placed into the Sleep state or a Removal

Detection event occurs. For wake on USB, the A_DET# pin assertion can be utilized by the system.

If the S0 control is ‘0’ and the UCS1002 is in the Active state, the A_DET# pin will be asserted

regardless if a portable device is attached or not. If S0 is '1', PWR_EN is enabled, and VS is not

present, the A_DET# pin will cycle if the current draw exceeds the current capacity of the bypass

switch.

5.4.2

Interrupt Blanking

The ALERT# and A_DET# pins will not be asserted for a specified time (up to tBLANK) after power-up.

Additionally, an error condition (except for the thermal shutdown) must be present for longer than a

specified time (tMASK) before the ALERT# pin is asserted.
