Current usage of th PCF8523

Contributor I

I am investigating a current product issue and need more information on the supply current of the PCF8523.  The device is in in the power mode with the power management enabled.  PM 2:0 [000].  The supply voltage is 3 volts.  I understand that the typical current is 1200 nA.

I would like to have any temperature related data for current usage over the device's temperature range. I am being asked for the battery life of the coin cell and I don't feel the specification gives enough information.

Hello James,

Unfortunately, we do not have such characterization.

In this case the datasheet specifies 150 nA @25C & 3.3V and 500 nA from -40 to +85C & 2V – 5V.


Please accept my apologies for any inconvenience.
