Tool/software:
Hi TI Experts,
I am seeing an issue with my LEDs that are being driven by an LP5036 when testing at -45C.
In that condition, all of our LEDs are going dark. I looked through the datasheet and I didn't see a low temp thermal disable. However it may be undocumented. Can you confirm if there is a low temperature disable threshold for this part?
Thank you,
Rob
Hi Rob,
The chip doesn't have the low temperature disable or thermal disable function. But -45C is out of the recommended operation temperature range.
To figure out whether there is spec derivation, could you measure the voltage on the IREF terminal and capture the output current waveform?
Besides that, may i know what the end application is that requires the device working in -45 temperature?
Best regards,
Felix
