LM9061: Points to consider when using this product

Taroimo
Intellectual 610 points
Part Number: LM9061

Dear TI team

 

Is the following understanding correct when using "LM9061"?

Please advise if there are any other points to consider.

 

① The "ON/OFF" pin of "LM9061" can be asserted at a voltage -0.3V lower than the "Supply voltage" (VCC) of "LM9061".

 

② For the Output Voltage (gate voltage) when the "ON/OFF" pin of "LM9061" is asserted, check "figure 5" in the data sheet.

 

③The output (source voltage) of the MOSFET connected to "LM9061" is the value obtained by subtracting the voltage drop due to the on-resistance of the MOSFET from VCC (drain voltage).

 

Best Regards,

Taroimo

    Hi Taroimo,

    Thanks for reaching out. Please see the responses below. 

    Answer to the question 1:

    Recommended Operating Condition for ON/OFF input voltage is shown below.

    Logic voltage levels for the ON/OFF pin are shown below. 

    Answer to the question 2:

    Yes

    Answer to the question 3:

    The LM9061 monitors the voltage drop from drain to source, VDS, across the MOSFET. Pin 2 measures the drain voltage of the MOSFET and Pin 1 measures the source voltage of the MOSFET.
