Slew rate control - TWL5030 embedded on TI SDP3430

Hi,

Is it possible to configure the power slew rate (negative) on the TI SDP3430, through HW registers, configuring embedded TWL5030 or else ?

I need to control the Power-OFF delay for an external MMC memory (vdds_mmc1):

  • By default, the board slew rate (3V -> 2.4V) is about 1.2ms
  • I need a slew rate (3V -> 2.4V) around 500us

 

Thanks in advance,

Rodolphe
