XC6801 Series
ETR2502-005
500mA 1 Cell Li-ion and Li-Po 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 and Lithium polymer
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 Lithium-ion and Lithium polymer 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 LIM pin or 500mA (MAX.) for H level, the series is ideal 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.

■PIN CONFIGURATION
* The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and
metal masking so as to enhance mounting strength and heat release. If the pad needs to be connected to
other pins, it should be connected to the VSS (No. 2) pin.

<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 LIM pin.
LIM ”H” level input:475mA(TYP.)
LIM ”L” level input:95mA(TYP.)
<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 ISEN pin voltage to detect the charge termination. When
the comparator sees that the ISEN pin voltage is less than 1.2ms (charge termination detect time), the IC enters stand-by mode.
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.

XC6801 Series
■OPERATIONAL EXPLANATION (Continued)
<Charge Condition Status>
The /CHG pin constantly monitors the charge states classified as below:
●Strong pull-down: I/CHG=10mA (TYP.) in a charge cycle,
●Weak pull-down: I/CHG=20μA (TYP.) in a stand-by mode,
●High impedance: in shutdown mode.
<Connection of Shorted BAT Pin>
Even if the BAT pin is shorted to VSS, a trickle charge mode operates in order to protect the IC from destruction caused by over
current.
<Under-voltage Lockout (UVLO)>
The UVLO circuit keeps the charger in shut-down mode until the input voltage, VIN, rises above the UVLO voltage. Moreover,
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 VIN Pin>
A backflow prevention circuit protects against current flowing from the BAT pin to the VIN pin even if the BAT pin voltage is
higher than the VIN pin voltage.

■NOTES ON USE
1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output
current. Please wire the CIN as close to the IC as possible.
3. Torex places an importance on improving our products and their reliability.
We request that users incorporate fail-safe designs and post-aging protection treatment when using Torex products in their
systems.
