Other Parts Discussed in Thread: LM5165
Hello Team,
when controlling the EN pin of the device directly from a uC and providing Vin separately it is possible that V_enable violates the abs max ratings of Vin+0.3V. For instance in case of Vin having not turned on yet. Or Vin being 3.0V but V_enable 3.3V+5%.
What is you recommendation? Would a 1kOhm resistor limit the current such that this operation will be OK. The 1k resistor should prevent the ESD cell from conducting extensive current. In case this is the issue...
many thanks
Lutz
