Note:
All the registers from address 0x19 to 0x2C are read-only.
7.9.1 Standby Mode - Power Consumption
In Standby Mode 1 there is a timer based accurate measurement every Ta seconds. The device itself stays in idle-mode as long as it does not
get a different command from the SPI interface. Internal oscillator frequency is typically foscint=262 kHz to reduce power consumption as long as
the timer runs. After every time out of Ta secs, it performs accurate measurement of current, voltage/ temperature. Data ready is signaled to
microcontroller through an interrupt signal on INT and goes into STOP state.
In the SBM the following equations hold:
Tsbm1 = Ta= 10s (default value is 10secs); the power consumption is valid for this setting. This is the period of the repetition rate in SBM 1
and SBM2.
T
sett ≈ 2ms (depending on external capacitors). This is the time required by the analog part to settle when the new measuring period is
started. Any measurements performed during T
sett produce invalid results.
T1 = 3ms (by default setting, every third measurement is sent to microcontroller in the SBM mode 1) is the time needed to perform the first
measurement.
T
meas =Tsett +T1 is the total active time needed to get a valid result.
DRSBM = T
meas/Tsbm ≈ 5ms/10s. This is the ratio of repetition time versus the active time (Device in NOM mode).
Power consumption = (DRSBM*NOM mode power consumption) + ((10s-5ms)/10s)*Stop mode power consumption)
