Detailed Description

Interface to allow recording of the drawn current in a user defined resolution.

Note

Keep in mind that the data recording may be performed by the CPU of the system to monitor - thus keep power consumption for the recording low!

The LTC4150 driver will only track total charge transferred (separately for charging in discharging direction). However, there are use cases that required more precise data recording, e.g. a rolling average of the last minute. This interface allows application developers to implement the ideal trade-off between RAM, ROM and runtime overhead for the data recording and the level of information they require.
