First question asked Welcome!

Hello

We are using the TLI493D. For safety issues we implemented a specific power supply for the TLI493D. In this case we can perform a power cycle to have a defined restart. Unfortunately we don't understand how the specification on datasheet page 9 does work:

Normally, a minimum time is needed for succesfull power cycle or reset. But on the datasheet, a max of 400us is defined with ramp. How does that work?
Thanks for any help!

Best regards
Marcel

Hi @Marcel ,

The Availability Power Cycle (APC) time defines basically the time for which the IC can work with a supply voltage under 3.3V, after a correct power up of the IC.

This means if the IC is working after a correct power up within 10µs the supply voltage can have a break down of a duration of max. 400µs without the need to perform the correct power up within 10µs again.

Thanks and best regards
