Other Parts Discussed in Thread: PMP4494
Dear Sir:
Reference to PMP4494, EN_N is pulled high to 3.3V. But it is asked to set ative low by reference to SPEC.
So how should I set EN_N ?
Thank you and expect your reply.
best wishes,

Hello Faith,
EN_N is an active low input, therefore you need to use either way a GPIO with a LOW state or a pull-down resistor. to disable the device it is enough to leave the input floating or connecting to a pull-up resistor.
