TPL5111: Using TPL5111 as long interval one-shot

Stephen Tomporowski

Part Number: TPL5111

This is a military application and I would like to use the TPL5111 as a long interval (25 to 300 seconds) one-shot. However, If I'm reading the datasheet correctly, keeping EN/One-shot low, it will immediately give a pulse on power-on. Is this the case? If so, that won't work for my application. Is there something else?

Thanks...Steve

Hi Steve,

Your understanding is correct. Unfortunately the output pulse at power-on cannot be disabled for this device.

I've seen interest in disabling the one-shot at power-up so that is only produced by the external trigger, I'll be sure to share this feedback with the internal team for the next gen product.

Kind regards,
Lane

Thanks, Lane. I'll just have to look for something else.
