Hello,
In the customer the GD output was not latched low when boost converter was stabled.
The GD output was latched low when VGL output is stabled.
In the customer sequence is the following.
Boost Converter in regulation ---> (about 3ms) ---> VGL output in regulation ---> (about 1ms) --->GD output latched low.
Does the GD output has delay?
I can send the schematics and waveform if you contact to the following e-mail address.
