alternative to MAX40200
(1/1)
mrpackethead:
Any suggestions for an alternative for a max40200 which is an ideal diode used in a battery backup for a low voltage/low currnet circuit.
ThomasDK:
A mosfet?

You need to make it clear what you are trying to do...

I have a low power circuit,  it has duty cycle of about .02% where it pulls 70mA. the rest of the time it is around 3uA.    Nominal power requirement is a Vdd of 3.3V

The primary power source will be a USB 5V supply.   ( because they are everywhere ). THe backup power supply will be some AA Alkaline batterys ( probably 2 ) which i'll connect via a DC/DC converter  ( Alkaline cells start at about 1.6V, and end of useful life is at abogtu .8V, so you do reallyu need to convert )
