Issue regarding disable input in Driver 2EDs8265hxuma1

[sabu31]

Dear All,

I need to give a burst of PWM for some duration and then turn it off for a half bridge inverter.

The PWM is generated using TL494 and the driver used is 2EDs8265hxuma1. A microcontroller signal (3.3V) is used for disabling/enabling the driver. However, once the driver is disabled (by giving high input to it), the driver does not get enabled. What could be the issue. The Vcc input to the driver and TL494 is 12V.

Thanking you.

Hi,

Schematic, please.

Did you measure power supplies and ENABLE signal voltage? Give values.

Klaus

The Enable Signal voltage is 3.3V.

The Input PWM signal to driver and the VDD is 12V

Hi,

no schematic...
no prove that the values are measured, so I have to assume they are guessed.

No complete information, impossible to help.
I don´t want to bother you with the same questions repeated.

Bye
