DATASHEET

Table 3.3, "Electrical

Specifications"



Changed tDET_CHARGE from 400 ms to 800 ms typ and

changed condition from CBUS = 220 µF to CBUS = 500 µF

max.



VS Leakage Current changed from 0.8 µA typical to 2.2 µA.



Changed IBD_1 and IBD_2 from TBD typ to 0 µA typ and from

1.5 µA max to 2 µA max



Changed ITST to ITEST and changed typ from 165 to 190 mA.



Changed tON_PSW from 3 ms to 0.75 ms typical and

tOFF_PSW_INA from 1 ms to 0.75 ms typical.



Spec changed for tHD:DAT. 0 µs min has condition when

transmitting to master. New row added with 0.3 µs min with

condition when receiving from master.



New characteristic: Bus Free Time Stop to Start, Start Setup

Time, Hold Time, Setup Time, Clock Low Period, Clock High

Period

Data Fall Time -> Clock / Data Fall Time

Data Rise Time -> Clock / Data Rise Time

Table 3.4, "ESD

Ratings"Section 3.1



Charged Device Model: changed from 200 V to 500 V

Note 5.1



Added note: In order to transition from Active state Data Pass-

through mode into Sleep with these settings, change the M1,

M2, and EM_EN pins before changing the PWR_EN pin.

Table 5.1, "Power States

Control Settings",

Section 5.1.2, "Sleep State

Operation",

Section 6.1, "USB High-

speed Data Switch"



The high-speed switch is open in Sleep.

Section 5.2.2, "VS Source

Voltage"



Added.

"Legacy 1, 3, 4, and 6

Charger Emulation Profiles"



Legacy 6 profile has been defined.

cont.

Section 9.4, "Data Pass-

through (No Charger

Emulation)"



Data Pass-through persists until M1, M2, or EM_EN controls

are changed. It is no longer affected by PWR_EN. Added

application note: When the M1, M2, and EM_EN controls are

set to ‘0’, ‘1’, ‘0’ or to ‘1’, ‘1’, ‘0’ respectively, Data Pass-

through mode will persist if the PWR_EN control is disabled;

however, the UCS1002 will draw more current. To leave Data

Pass-through mode, the PWR_EN control must be enabled

before the M1, M2, and EM_EN controls are changed to the

desired mode.

Section 9.6, "BC1.2 CDP"



BC1.2 CDP mode uses constant current limiting. Added

application note: BC1.2 compliance testing may require the

S0 control to be set to ‘0’ (Attach and Removal Detection

feature disabled) while testing is in progress.



Added application note: When the UCSX100X is in BC1.2

CDP mode and the Attach and Removal Detection feature is

enabled, if a power thief, such as a USB light or fan, attaches

but does not assert DP, a Removal event will not occur when

the portable device is removed. However, if a standard USB

device is subsequently attached, Removal Detection will

again be fully functional. As well, if PWR_EN is cycled or M1,

M2, and / or EM_EN change state, a Removal event will

occur and Attach Detection will be reactivated.
