APPLICATIONS INFORMATION
Battery Charge Termination Voltage
Battery charge termination voltage is set by a
resistor Rbtv connected from BTV pin to AGND as
shown in Figure 5. The battery charge termination
voltage is estimated as the following equation:
Rbtv is selected based on the battery voltage rating.
1% accuracy resistor is recommended for Rbtv.
LED Status Indication
4 LEDs ON/OFF and flash show the charge status
and the remained capacity level as shown in the
table 2. The LED status is based on battery voltage
and operation modes. When battery voltage is low,
LED1 is flashing. In charge mode, when a battery is
fully charged, flashing stops and all the 4 LEDs are
solid on.
Battery level voltage shift (BLVS pin)
LED1-4 voltage thresholds are adjusted from HZ
mode during charging and discharging based on
the compensated impedance. Those thresholds are
programmed by a resistor connected from BLVS
pin to AGND as shown in Figure 6. The following
equation shows the LED4 voltage threshold:
As long as LED4 is set, all the other 3 LED
thresholds is fixed as shown in the table 3:
Table 3: 4 LED Voltage Thresholds
Input Current Limit
An external resistor is used to set the input current
limit connected from ILIM pin to AGND as shown in
Figure 7. Input current limit has built-in soft startup
and current foldback control loop. The input current
limit is estimated as the following equation:
