One way to make the battery system efficient is minimizing the energy usage while the system is runing or is in standby-mode. This can be realized by limiting the current drawn by the system from the battery. Thanks to Diotec's new LDO Voltage regulators LDI8119EN and LDI8233EN with Enable-function it is possible to switch-off the system, thus the input current will be limited usually up to 1.0 µA.

This simple solution will boost the efficiency of the battery system and prolong battery life. Due to the shutdown current of 0.4 µA - 1.0 µA the LDI8119EN and LDI8233EN are suitable in all battery management applications. Please refer to following PDF file for more detailed information.
