Hi Dear,

The customer uses TLV9101 chip, and the system power supply is 12V to 30V. When the power supply is 12V, the chip cannot start. What is the reason

30 V will destroy the chip.

Please show the schematic.

Anna,

30V is way too high. This would likely permanently damage the device. After that, it shouldn't work at 12V

How do they know that it doesn't start at 12V, what are the symptoms?

Hey Anna,

The product page on ti.com shows that a higher voltage alternative is the OPA990. Please have the customer try with a op that is rated for 30V, like the OPA990.

All the best,
Carolina
