LM5066I: Shutdown current specification?

Hi Gordon,

Thanks for reaching out!
It should be less.. Let me check and get back to you.

Hi Gordon,

Sorry, we don't have data for this parameter.
Can you please let me know the importance of this value in your system design. If needed, I can check for couple of devices and provide you a typical number.

Rakesh,

Our system is battery powered, and the current drain will discharge the battery. Since it must be stored for a long period of time, we want the drain to be as low as possible. We checked on the Evaluation Board, and it appears the current is the same whether the device is enabled or not. So we have decided not to use it, but to go with a different design approach.

Thanks

Gordon

Hi Gordon,

Got it.
Does a device like LM5060 (without telemetry) works for you? It takes only 9uA in disable mode. or LM5069 (480uA disable current) suit?
what is the max. battery voltage?

Best Regards,
Rakesh

I'll look at those, but the telemetry is really attractive, and we would have to add it somehow. The battery is 9 lithium ion cells in series, so maximum of 37.8V.

Other option is solution like INA233. Please post in SENSING forum if you have query on INA233
