CD40109B: 3.3V PWM to 12V PWM

Part Number: CD40109B
Other Parts Discussed in Thread: UCC27517, TLV1805

Hello Team,

I am generating a 3.3V PWM signal using ESP32 I need to convert that to 12V PWM signal. I am planning on using CD40109B but i do not know if it would work. Could you kindly let me know if it would work if not then any other method to do the same would be much appreciated.

Thanks

The CD40109B will work, but is slow at 3.3 V, and has more channels than needed.

Alternatively, use a gate driver like the UCC27517, or a comparator like the TLV1805.
