What is the preferred mode to operate the MAX14921 between cell measurements?
- For example, lets say the customer only reads the cell voltages every 10 seconds. Converting the voltage only takes a short time out of the long interval.
- In what state should the part be held in - Sample, Hold, or other when not being used?
- There is no problem keeping the MAX14921 in sample or hold mode when not being used. However, the part will continue to draw normal operating power when kept in these modes. Typically, the part is powered from the battery stack and, as such, it is desirable to keep it in a low-power state as often as possible. We recommend toggling the EN input to keep the part in a low-power state when it is not being used. This allows the customer to enable it for reads and then significantly reduce the power draw when cell voltages are not being read.
