TPL5111: Way to extend the pulse width on DRVn

Part Number: TPL5111

Hi Team,


I am posting this inquiry on behalf of our customer:

The customer need the power on feature of the TPL5111 to initiate the pulse or logic high. Then use that to enable a DC switch and power up another circuit. Then the customer would like the circuit to continue to 'extend' the duration of the Logic High - for as long as a user needs the circuit energized. When done - then wanted to shut the TPL5111 down by not extending the pulse.

Is there any way on extending the pulse width on DRVn?

Note; The customer already tried using the Delay/M_DRV by applying VCC  - but it does not seem to extend the pulse width.


Let me know if the customer application above is possible and how can this be achieved without using other ICs


Thanks!

Jonathan

  • Hi Jonathan,

    The initial condition and pulse width of the TPL5111 cannot be changed.

    Typically a timing diagram of what you are trying to do is helpful, but we might not be able to come up with a solution here anyways.
