LM61460-Q1: EN pin logic

Part Number: LM61460-Q1
Other Parts Discussed in Thread: LM61460, TLIN1028-Q1,

Hi team，

My customer is using LM61460-Q1 in their project. They would like to use TLIN1028-Q1's internal LDO output(3.3V) to control the enable function of LM61460. I'd like to know whether they could connect EN pin with 3.3V output of the LDO directly or any external pull up/down resistor or capacitor have to be used?

Thanks,

Scarlett

Hello

At first glance i do not see anything wrong with that.

As long as the input voltages of the two devices come from the same source and are

not sequenced. You can put a 10k series resistor between the EN and the LDO to be safe.

Thanks
