Other Parts Discussed in Thread: TIDA-01605, , UCC21530
Dear TI expert：
I'm working on the TIDA-01605 project,Find that the UCC21530-Q1 EN pin is always low(refer to GND)
When UCC21530 and ISO7721QDRQ1 are used, the device is in the default state (VG1,VG2 float,G1,S1,G2,S2 float), and the U8-7 pin is low (refer to -4vb), so the U7-2 pin output is low (refer to GND), and thus the U6-5 pin is low. If so, no matter how VG1 and VG2 change, G1 and G2 will not have high levels.
Am I wrong? If so, please indicate
thank you
