TPS3808: alternate device with lower tolerance on reset time pulse

Part Number: TPS3808
Other Parts Discussed in Thread: TLV803E

Hi all

My customer is using the TPS3808 and they find the reset time can vary from 17ms .... 51ms.

Is there a device with a tighter tolerance for the reset time ?

Best regards

Hello Ueli,

These time delay variations are very typical. Ade vice with a fixed internal timing such as TLV803E may be slightly better here.

Thanks,

Masoud

Hello Masoud

Thank you for the quick reply and yes, I see the reset pulse has 1:2 ratio from min to max for the TLV803E or other devices with fixed reset pulse length.

Best regards
