Resolved! Thermal Characteristic of LDO
The thermal characteristics of the LDL112PU33R show the junction to ambient thermal resistance (JA) and the junction to case thermal resistance (JC). However, the junction to board thermal resistance (JB) is missing. We need this characteristic for t...
L6472 overcurrent error due to ESD pulse during EMC test
We use this part L6472 more than 10 years, and in the latest design we have serious troubles with ESD. The device current limit is set to highest level of 6A, but during an ESD pulse, it throws the message "over-current error", even if the motor wire...
