TPS61310: Reset timings

Matthias Fend

Part Number: TPS61310

Tool/software:

I could not find any information in the data sheet as to whether or how long one has to wait before accessing the I2C interface again after a software reset was triggered (BIT7 in REGISTER0).
I also couldn't find any information about whether you have to wait a certain amount of time after a hardware reset. Only the minimum duration of the reset pulse is described.

Can you confirm that in these two cases no waiting time is actually required?

    Hi,

    It may require few clock cycles to finish reset process on digital circuit section, but for analog circuit section, it may require longer time like 50us~100us for parasitic circuit discharging.

    So it's better to wait about 100us to resume device for normal operating after reset triggered.
