1 Cell Li-ion Battery Linear Charger IC with Constant-Current/Constant-Voltage

■GENERAL DESCRIPTION

The XC6801 series is a constant-current/constant-voltage linear charger IC for single cell lithium-ion batteries. The XC6801

includes a reference voltage source, battery voltage monitor, driver transistor, constant-current/constant-voltage charge circuit, overheat protection circuit and phase compensation circuit. The battery charge termination voltage is internally set to 4.2V ±

0.7% and the trickle charge voltage and accuracy is 2.9V ±3%. In trickle charge mode, a safe battery charge is possible

because approximately only 1/10 of the full charge current is supplied to the battery. As it is possible to select a highly

accurate charge current of either 100mA (MAX.) for L level input to the L

for applications where the charge is from USB. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s

charging state via connection to an external LED.

■APPLICATIONS

■OPERATIONAL DESCRIPTION

Constant-Current Charge (CC)

Constant-Voltage Charge (CV)

V V

Charge Termination

<Charge Cycle> If the BAT pin trickle voltage is less than 2.9V(TYP.), the charger enters trickle charge mode. In this mode, a safe battery charge is possible because approximately only 1/10 of the charge current is supplied to the battery. When the BAT pin voltage rises above trickle voltage, the charger enters constant-current mode (CC mode) and the battery is charged by the programmed charge current. When the BAT pin voltage reaches 4.2V, the charger enters constant-voltage mode (CV mode) automatically. After this, the charge current starts to drop and when it reaches a level which is 1/10 of the programmed charge current, the charge terminates.

<Setting Charge Current> The charge current can be set from 475mA（TYP.）or 95mA（TYP.）by the L

<Charge Termination> The battery charge is terminated when the charge current decreases to 1/10 of the full charging level after the battery pin voltage reaches a float voltage. An internal comparator monitors the I the comparator sees that the I A driver transistor turns off during the stand-by mode.

<Automatic Recharge> In stand-by mode battery voltage falls. When the voltage level at the battery pin drops to recharge battery threshold voltage

4.05V(TYP.) or less, the charge cycle automatically re-start after a delay of 1.7ms. As such, no external activation control is needed.

■OPERATIONAL EXPLANATION (Continued)

<Charge Condition Status> The /CHG pin constantly monitors the charge states classified as below:

●Strong pull-down: I

●Weak pull-down: I

●High impedance: in shutdown mode.

<Connection of Shorted BAT Pin> Even if the BAT pin is shorted to V current.

<Under-voltage Lockout (UVLO)> The UVLO circuit keeps the charger in shut-down mode until the input voltage, V in order to protect the battery charger, the UVLO circuit keeps the charger in shut-down mode when the voltage between the input pin voltage and BAT pin voltage falls to less than 30mV. The charge will not restart until the voltage between the input pin voltage and BAT pin voltage rises more than 100mV. During shut-down mode, the driver transistor turns off but a failure detection circuit operates, and supply current is reduced to 8μA.

<Soft-Start Function> To protect against inrush current from the input to the battery, soft-start time is optimized and internally set (150μs, TYP.).

<Backflow Prevention Between the BAT Pin and the V A backflow prevention circuit protects against current flowing from the BAT pin to the V higher than the V
