LM5036: On/Off control

Part Number: LM5036

Hi team we are considering making a project using lm5036.
But we have a question about one thing.

How can we perform the on/off operation safely via an external mosfet?

also UNVLO, OVP, OTP and CBC protections must also be functioning properly.

what are you suggestions? 


Thanks.

    Hi,

    UVLO, OTP and CBC are non-configurable protection functions. OVP and ON_OFF are configurable and can be set up as either latching or non-latching response to faults arising from OVP OCP, OTP, as described by section 7.3.17 in the LM5036 data sheet. From your description, I assume you want to set up the ON_OFF as latching and then be able to reset the latch using a MOSFET?

    The latch is reset when UVLO<1.25V, which means you can connect an N-ch, logic-level, signal MOSFET (2N7002) drain to UVLO and use whatever control signal you choose to reset he latch by apply 5V to the MOSFET gate.

    Regards,

    Steve
