Hi Team, 

Just want to check when EN is pulled low, will all REGs be set to default value? Thanks.

  • Hi Given,

    Let me confirm it in the lab and get back to you by tomorrow.

  • Hi Given,

    It depends on which flavor of TPS65132. For example:

    For TPS65132S, if SYNC pin remains high, it will retain register settings even when EN is pulled low but if SYNC pin is low, device will lose register settings when EN is pulled low.

    For TPS65132W, register settings are retained as long as either ENP or ENN is high but if both ENP and ENN are pulled low, register settings are lost.

    Kind Regards,

  • Hi Given,

    So here it goes for various devices in the family:

    For TPS65132A, TPS65132A0: register values are retained as long as Vin is above UVLO level even if ENP/ENN are both pulled low.

    For TPS65132B TPS65132B0, TPS65132B2, TPS65132B5, TPS65132L, TPS65132L0, TPS65132T6, TPS65132W: Register values are retained as long as either ENP or ENN is high. If both ENP and ENN are pulled low, register contents are lost.

    For TPS65132S:  if SYNC pin remains high, it will retain register settings even when EN is pulled low but if SYNC pin is low, device will lose register settings when EN is pulled low.

    Kind Regards,
