TPS68470: VCM_OUT and I2C timing

Satoshi Yone

Part Number: TPS68470

Hi, Team,

I have a question for TPS68470.

Can TPS68470 control the output timing of VCM_OUT and I2C command? It takes 4.64 msec until the command is sent to the VCM Driver after VCM_OUT rises. A customer need min 12 msec before VCM_OUT rises.

Best Regards,
Satoshi Yone

Yone-san,

The i2c master can control when to send the enable command, but there are no timing settings in the PMIC for the delaying the VCM LDO.

Best Regards,
