All,

One of my customers has some questions on the ucd90160a

What is the minimum delay from device power on to turning on the first rail

What is the resolution for the time steps when sequencing power supplies

How can these devices be programmed in bulk for production

 

Thanks,

Regards,

Joe

    Hello

    Please see my comments;

    1. it takes about 20ms for device to finish reset and initialization. If there are no other conditions set for the given rails, it would be around 20ms to turn on the first rail

    2. The sequencing state machine runs at 500us per 16 rails.

    3.  They can be programmed by I2C bus on the ICT if they prefer program post-soldering. Some company can help program the parts pre-soldering with little premium.
