5.3. Higher Precision for the Voltage Control
The voltage drop through the sense resistor R5
offsets the voltage measurement. In most battery
charging applications, this offset is not taken into
account because the error is negligeable com-
pared to the end-of-charge voltage due to the fact
Figure 5 : Precise Output Voltage Control
In this schematic, the 0V reference is defined as
the common point between the sense resistor, the
0V Output Voltage, the foot of the resistor bridge
8/13
that the charging current value decreases drasti-
cally during the final phase of the battery charging.
But in other applications needing highest possible
precision in voltage control, another connecting
schematic is possible for TSM101 as shown on
figure 5.
R6/R7, and the ground (pin 4) of the TSM101.
TSM101A (1% internal voltage reference preci-
sion) is required in such applications.
