VR5510 Shutdown

ajnas-c — Mon, 09 Jan 2023 07:48:19 GMT

Hi,

Our requirement is that the device must be powered OFF completely when the ambient temperature exceeds 125 degrees and automatically turned back ON when it drops below 120 degrees. Is there any feature available in VR5510.

Please let me know.

Regards,

Ajnas

Hi Ajnas,

The VR5510 does not have such a feature. There are available various overcurrent detections and thermal shutdowns at 155°C min. for LDOs and BUCKs.

Best regards,

Tomas

Hi Ajnas,

You can find a detailed description in chapter 17 of the VR5510 datasheet.
