I am driving a SLG59M1440V with 3.3V rail on D/Vin, and transitioning from 0V to 3.3V driven through an 86.6K resistor to the ON pin.
I observe the S/Vout ramping up to approximately 3V before falling with an RC decay to nearly 0.5V. This cycle occurs a random number of times before the output ramps successfully up to 3.3V and stays.
It appears that the switch is toggling on/off. During this event, I have probed the ON pin and it is held at around 1.1V for the duration of the cycling, and rises to 3.3V once the output rises to 3.3V as well. All the while the 3.3V is constant on the D/Vin pin and on the other side of the 86.6k resistor.
Can you please help me understand what is going on and what could be causing this behavior?
In the attached file:
- Green is D/Vin = 3.3V
- Magenta is Signal on 86.6k resistor = 3.3V
- Yellow is ON pin = 1.1V
- Blue os S/Vout pin = Glitching from 0.5V->3.0V
