TWL6032 External regulator sequencing control - REGEN1 & REGEN2

Perumal Srinivasan

Other Parts Discussed in Thread: TWL6032

Hi,

We are using TWL6032 in our design along with OMAP4460. Due to various power & sequencing requirement, we have used 2 additional regulators other than TWL6032. To control the sequence for those external regulators, we need to use REGEN1 & REGEN2 signals of TWL6032.

Let us know,

- Whether these two signals are used by TWL6032 with its default OTP configuration ? If yes, what is the sequence of these two control signals with respect to other voltages generated by TWL6032

- If these are not enabled/controlled by TWL6032 with default OTP configuration, how can we program this OTP memory?

Hi, these signals are configurable at OTP level; to understand their behavior you need to tell me which OTP you are using. If you give me the exact part number you are ordering I'll be able to tell you.

Best regards, Alain.

Hi Alain,

Thanks for your response. TWL6032A2B0YFF is the exact part number we are ordering.

Ok, so in this case REGEN1/2 are both going from low to high level ~5mS after PMIC wakes up i.e. at the very beginning of power up sequence and go back to low level ~8mS after power down i.e. at the very end of this sequence,

Best regards, Alain.
