Hi Team,

Do you have experience that when Vin < 5V that we use MOSFET to provide the quickly discharge path? If so, can you provide the reference circuit or block? Thank you.

Hello Roy,

Thanks for the inquiry. A rapid discharge circuit using a MOSFET should be relatively easy to implement, A N-channel FET with the drain connected to the node to be discharged, source grounded and gate driven to the minimum VGS where Rds(on) is specified. You may want to add a series drain resistor to limit the current and dissipate some of the power if the capacitance to be discharged is high. Can you share the detailed application requirements?

Best Regards,

John Wallace
