TPS389006-Q1: Voltage drops - how to properly monitor power supply

Tom Levisse

Part Number: TPS389006-Q1

Hello I am a software engineer,

I observed a voltage drop when connecting power supply to a monitor PIN of TPS389006-Q1.

Does the monitor have low input impedance ?

How can I avoid this issue ?

Best regards,

Hello Tom,

I have confirmed the monitoring pins are high impedance. I have a few follow up questions:

1. Is there a large current draw when connecting the source to the pin

2. How severe is the voltage drop

Hello, thank you for your answer. I finally observed that the voltage drop was from another part of my circuit.
