Other Parts Discussed in Thread: UCC27531
Hello Guys,
Good day.
Our customer is encountering issue in their design using AM26LV31E differential driver. It works for high frequencies, but in low frequencies ( less than 1 Hz) its outputs pull down (gets back to zero). Do you know why this issue occurs?
See attached schematic. Device is named dif_drv on slide 6. It is connected to a UC2731 Gate driver, So, the pulse doesn't keep ON. It turns off and the output of gate driver shows -4 V ( turn off voltage according to the design). So, the maximum time that the output keeps ON is 2 sec. After that it turns off. Customer is using 0.01 Hz.
Thanks and regards,
Art
