MOSFET driver for controlling common cathode LEDs

[Remark]

Hello,

I have encountered a problem controlling 24V LEDs using a transistor. According to the common cathode LEDs configuration, I finished my design with N-channel and P-channel MOSFET drivers for high-side switching, where the MOSFET is turned on with a low signal and turned off with a high signal. However, when simulating the schematics, I noticed some voltage across the simulated 'LED' when the 'driver' is switched off. Could I ask where this voltage comes from and why it isn't zero or near zero when switched off?

Ummm… take a closer look at the “some voltage”: it’s 5.8ᴇ-5.

You do know how to read scientific notation, right?

That means 5.8 x 10^-5V = 5.8/100000 V = 0.000058 V = 58 microvolts.

That’s very much “near zero” in the context of 24V.
