ery Profile

Configuration

Selector 1

CFG_SEL1

AIO

This pin is used in conjunction with CFG_SEL0 to select

the power delivery profile of the device via an externally

connected RC circuit. Refer to Section 3.3, "Configuration

Selection (CFG_SEL0/CFG_SEL1)" for additional infor-

mation.

Source

Voltage

Select 0

VSEL0

OD8

This pin is used in conjunction with VSEL1 to select the

correct source voltage from the DC-to-DC or AC-to-DC

solution. VSEL1 and VSEL0 select the voltage value from

the supported voltage capabilities in ascending order with

VSEL0 being the least significant bit (see examples

below).

For example, if an adapter supports 5, 9, and 20 V capa-

bilities, the VSEL1 and VSEL0 selections will be as fol-

lows:

VSEL1 VSEL0

20 V

RESERVED

In another example, if an adapter supports 5, 9, 12, and

20 V capabilities, the VSEL1 and VSEL0 selections will

be as follows:

VSEL1 VSEL0

12 V

20 V

For a mapping of the VSEL1/VSEL0 voltage assignments

for each CFG_SEL1/CFG_SEL0 configuration profile,

refer to TABLE 3-3: 32-SQFN CFG_SELx Configuration

Assignments on page 21.

Note:

This function is only available in specific

device configurations.

Select 1

VSEL1

OD8

This signal is used in conjunction with VSEL0 to select

the correct source voltage from the DC-to-DC or AC-to-

DC solution. VSEL0 and VSEL1 select the voltage value

from the supported voltage capabilities in ascending

order.

Refer to the VSEL0 definition for additional information.

Note:

This function is only available in specific

device configurations.
