LP8866-Q1: Risk from EN=LOW and PWM=High

Kazuki Kuramochi

Part Number: LP8866-Q1

Tool/software:

Hello Expert,

Is there any risk for configuring this device's EN pin as LOW and PWM as HIGH?

I think EN=LOW shutdown all circuit block so there isn't any risk from this configuration except PWM pin ABSMAX violation if they disable VDD pin as well.

However, we'd like to make sure it just in case.

Best regards,

Hi, Kazuki

There is no risk for EN is low and PWM is high.

By the way, VDD needs to keep 3.3 when we discuss the EN and PWM logic.
