The USBLC6 starts conducting at 6V with 1 mA current, and if the source can supply 1A, then the clamping voltage goes to 12 V (and 17V at 5A). It is all in the datasheet. | |
| Mar 27, 2019 at 18:53 | comment | added | lulle2007200 | Maybe i worded my initial question poorly. The USBLC6 Datasheet claims a breakdown voltage of 6V between GND and VBUS. If there is a let's say 10V voltage difference between GND and VBUS, wouldn't the USBLC6 clamp it to 6V? And would the LTC4361 trigger from 50ns ESD events? | |
