LM5110: Output logic

Part Number: LM5110
Other Parts Discussed in Thread: LM5111

Hi Team,

LM5110-3M is composed by Inverting “A” OUTPUT and Noninverting “B” OUTPUT.

During UVLO mode what is the logic of output “A” and “B”, all the Low or following the table 2?

Under forum maintenance it will be very helpful if you can contact me via email 

Best Regards,
Tom Liu

  • Hello Tom,

    Hopefully you can see this message. For this device, UVLO always pulls the output low. For driving PMOS, many people would like the UVLO to pull high to turn off the PMOS. If that is what you are looking to do, LM5111 has that feature. Although, it doesn't have the split grounds.
