Other Parts Discussed in Thread: ISO1212, ISO1211
Our customer is having troubles with the isolator ISO7760DBQR in the isolation test. They have a loop when the supply is off and there is a high level in any input pins. The device does not support 28V in the inputs without voltage in the supply. When they apply 28V in the input, the internal diode (datasheet figure 23) provoke the loop with GND and VCC.
Do we have an alternative which can support 28V in the inputs without voltage in the supply?
Thanks and regards,
