LP5569: EN/PMW pin Function

user6519235

Part Number: LP5569

Hello,

I have a question about the datasheet [6 Pin Functions].
Please let me know the internal circuit of EN/PWM pin.
Does the EN/PWM pin have a pulldown resistor inside?

Best regards,

Hi Monet,

So please clarify the output condition on the host side.

What are the specifications that connects to the EN/PWN pin? Pulldown? Pullup?

Best Regards,

Hyodo

Hi Hyodo,

The high level voltage will enable the EN/PWM pin.

In the internal circuit of EN/PWM pin, It can be equivalent to a be pull-down resistor.
