Other Parts Discussed in Thread: UCC27524, UCC27624
My customer has some questions about VDD and GND pin. Customer use the diode gear of multimeter to measure the internal diode between VDD and GND.
When the red probe on the VDD and black probe on the GND pin, the read voltage is 1.1V. When the red probe on the GND pin and black probe on the VDD pin, the read voltage is 0.5V.
Customer measure two units of UCC27524, and not soldered on the board. The read voltage are the same.
Could you please kindly confirm this phenomenon? Customer has some concerns that it may have some additional leakage flow from the VDD to GND.
If this phenomenon is normal, could you please help me understand why there have 1.1V diode between VDD and GND pin?
