Part Number: LM3886

Tool/software:

Hi team,

is there any power sequences requirements for LM3886?  customer plan to use 18V as positive voltage and -48V as negative voltage. But for power up sequences, there is no specific requirements. Could you pls help to comment on the power sequences requirements for supply voltage? Thanks!

    Hi Rayna,

    There's no specific power sequence for this device. Based on the data sheet explanation, it also says that under-voltage protection helps to bring up the device in a known state after the supplies are fully powered up.
