For instance:



PDO_FLEX_V1 = 10b0100100010 → 14.5 V



PDO_FLEX_V2 =

10b0110000110 → 19.5 V

PDO_FLEX_I is defined in a specific 10-bit register, value is being expressed in 10 mA

units. For instance:



PDO_FLEX_I = 10b0011100001 → 2.25 A

Monitoring configuration in NVM



T_PDO_Transition can be configured from 20 to 300 ms by increments of 20 ms (0 is

not recommended). Default value is 240 ms.



T_Transition_to_0V can be configured from 84 to 1260 ms by increments of 84 ms (0

is not recommended). Default value is 168 ms.



Vshift_High can be configured from (5 to 20%). Default value ranges from 8% to 12%.



Vshift _Low can be configured from (5 to 20%). Default value is 10% for all PDO.

4.5

Discharge configuration in NVM

Both internal and external discharge paths are enabled by default. VBUS_DISCH control

pin is configured to drive a PMOS by default (active low).
