电源开关 ic - 配电 prog. usb port power controller emulation

Programmable USB Port Power Controller  with Charger Emulation

General Description UCS1002-1-BP-TR

The UCS1002 provides a USB port power switch for

precise control of up to 2.5 amperes continuous current

with over-current limit (OCL), dynamic thermal

management, latch or auto-recovery (low test current)

fault handling, selectable active low or high enable,

under- and over-voltage lockout, back-drive protection,

and back-voltage protection.

Split supply support for VS and VDD is an option for low

power in system standby states. This gives battery

operated applications, like notebook PCs, the ability to

detect attachments from a sleep or off state. After the

Attach Detection is flagged, the system can decide to

wake up and/or provide charging.
