XC6802 Series
ETR2501-006
800mA Single Cell Li-ion Battery Linear Charger IC
GENERAL DESCRIPTION
The XC6802 series is a constant-current/constant-voltage linear charger IC for single cell lithium-ion batteries. The XC6802
includes a reference voltage source, battery voltage monitor, driver transistor, constant-current/constant-voltage charge circuit,
over heat protection circuit, 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 charge to a battery is possible
because approximately 1/10 out of setting charge current is supplied to the battery. With an external R
current can be set freely up to 800mA (MAX.), therefore, the series is ideal for various battery charge applications. The series’
charge status output pin, /CHG pin, is capable of checking the IC’s charging state while connecting with an external LED.

OPERATIONAL EXPLANATION
Constant-Current Charge (CC)
Constant-Voltage Charge (CV)
<Charge Cycle>
If the BAT pin voltage is less than trickle voltage (TYP. 2.9V), the charger enters trickle charge mode. In this mode, a safe
battery charge is possible because approximately only 1/10 of the charge current which was set by the I
the battery. When the BAT pin voltage rises above the 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 by connecting a resistor between the I

<Charge Termination>
The battery charge is terminated when the charge current decreases to 1/10

the comparator monitors the I
termination detect time), the IC enters stand-by mode. A driver transistor turns off during the stand-by mode. In this state, a
failure detection circuit and a monitoring circuit of the battery pin voltage operates.
(*1)
The detect after charging completed: I
<Automatic Recharge>
In stand-by mode battery voltage falls. When the voltage level at the battery pin drops to recharge battery threshold voltage
(TYP. 4.05V) or less, the charge cycle automatically re-starts after a delay of (TYP. 2ms). 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 the V
by over current.
<Under-voltage Lockout (UVLO)>
The UVLO circuit keeps the charger in shut-down mode until the input voltage, V
Moreover, in order to protect the battery charger, the UVLO circuit keeps the charger in shut-down mode when a voltage
between the input pin voltage and BAT pin voltage falls to less than 30mV (TYP.). The charge will not restart until the voltage
between the input pin voltage and BAT pin voltage rises more than 100mV (TYP.). During the shut-down mode, the driver
transistor turns off but a failure detection circuit operates, and supply current is reduced to 10μA (TYP.).
<Soft-start Function>
To protect against inrush current from the input to the battery, soft-start time is set in the circuit optimally (150μs, TYP.).
<Manual Shut-down>
During the charge cycle, the IC can be shifted to the shut-down mode by floating the I
battery is reduced to less than 2μA and a shut-down current of the IC is reduced to less than 10μA (TYP.). A new charge
cycle starts when reconnecting the current sense resistor.
<Opened BAT Pin>
When the BAT pin is left open, the IC needs to be shut-down once after monitoring the CHG pin by a microprocessor etc and
