Detailed Description

Function Documentation

Cy_USBPD_BB_Enable()

void Cy_USBPD_BB_Enable

(

cy_stc_usbpd_context_t *

context

)

Enables the Buck-Boost regulation with soft start.

This function should be called to start the regulation with soft start sequence. Cy_USBPD_BB_Init() must have been called prior to this function.

Parameters

context

USBPD PDSTACK Context pointer.

Cy_USBPD_BB_Disable()

void Cy_USBPD_BB_Disable

(

cy_stc_usbpd_context_t *

context

)

Disables the Buck-Boost regulation.

This function resets buck-boost operation until Cy_USBPD_BB_Enable() is called.

Parameters

context

USBPD PDSTACK Context pointer.

Cy_USBPD_BB_IsEnabled()

bool Cy_USBPD_BB_IsEnabled

(

cy_stc_usbpd_context_t *

context

)

Buck-Boost regulation enable status.

This function returns the status of Buck-Boost regulation enable.

Parameters

context

USBPD PDSTACK Context pointer.

Returns

bool Buck-boost enable status.

Cy_USBPD_BB_IsReady()

bool Cy_USBPD_BB_IsReady

(

cy_stc_usbpd_context_t *

context

)

Buck-Boost regulation ready status.

This function returns the Buck-Boost regulation enable sequence done and regulator ready status.

Parameters

context

USBPD PDSTACK Context pointer.

Returns

bool Buck-boost enable status.

Cy_USBPD_BB_Init()

void Cy_USBPD_BB_Init

(

cy_stc_usbpd_context_t *

context

)

Initializes the Buck-Boost regulation.

This function should be called only during USBPD drivers initialization at power up.

Parameters

context

USBPD PDSTACK Context pointer.

Cy_USBPD_BB_PowerDown()

void Cy_USBPD_BB_PowerDown

(

cy_stc_usbpd_context_t *

context

)

Power Down the Buck-Boost block for power saving.

This function should be called only during Deep Sleep entry.

Parameters

context

USBPD PDSTACK Context pointer.

Cy_USBPD_BB_PowerUp()

void Cy_USBPD_BB_PowerUp

(

cy_stc_usbpd_context_t *

context

)

Power Up the Buck-Boost block for active mode.

This function should be called only during Deep Sleep exit.

Parameters

context

USBPD PDSTACK Context pointer.

Cy_USBPD_Fault_BbIlimDetEn()

void Cy_USBPD_Fault_BbIlimDetEn

(

cy_stc_usbpd_context_t *

context

)

Enable Buck-Boost inductor current limit protection.

Parameters

context

USBPD Context pointer.

Cy_USBPD_Fault_BbIlimDetDis()

void Cy_USBPD_Fault_BbIlimDetDis

(

cy_stc_usbpd_context_t *

context

)

Disable Buck-Boost inductor current limit protection.

Parameters

context

USBPD Context pointer.
