AVR451
The maximum input voltages to the ATtiny device must be below the supply voltage
of the ATtiny, and the differential voltage over the shunt (resistor dividers) must be
below the ADC’s voltage reference, which is 2.5V (0.1% accuracy). If the differential
voltage is low the internal gain stage of the ATtiny can be enabled to get better
readings.
3.3 Electronic load
The BC100 features two electronically controlled constant current loads (adjustable).
The loads are meant for development purposes: One load can be used to load the
output of the buck converters to verify that the ADC reads the expected current during
“charging” (no battery connected while the load is connected). The other load can be
used to verify that the correct current is read when the battery is discharged into the
load.
Figure 3-3. The electronic constant current loads (section of the BC100 schematics).
The ATmega644 board controller controls the electronic loads. The load current is
controlled by the duty cycle of the PWM (OC2A on TIMER 2). The electronic load is
will NOT endure very high currents, and the current flowing through the loads should
be limited so that it does not exceed the tolerances of the FETs (15W) and resistors
(2W). Warning: the components do not have any cooling area and may suffer from
thermal damage even below the recommended maximum power dissipation rating.
