TPS22930A: Load Switch Recommendation Normally On?

Part Number: TPS22930A
Other Parts Discussed in Thread: TPS22942, TPS22910A

Hello,

I am looking for a load switch like the TPS22930A; however, I would like one where the load switch is closed when 0V is applied and open when 3.3V is applied. Can you recommend a product which meets these requirements?

Thank you,

Hey High Speed Guy,

Thanks for reaching out on E2E!

Can you clarify your operating conditions? Are you looking for a device where the ENABLE (ON) channel is active low, where 0V applied on the ON pin turns on the device and 3.3V applied to the device turns it off?

Or, are you looking for a device where the power path is closed when 0V is applied to VIN?

Thanks,

Arthur Huang

Hi HSG,

Thanks for the clarification, I suggest looking at the TPS22916CL, TPS22910A or TPS22942.

Thanks,
