XC6801 Series ETR2502-003a 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 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. ■APPLICATIONS ● ● ● ● ● USB charge applications Charging docks, charging cradles MP3 players, portable audio players Cellular phones, PDAs Bluetooth headsets ■ FEATURES Operating Voltage Range : 4.25V ~ 6.0V Charge Current : 100mA (MAX.) @ LIM pin=L (externally set) 500mA (MAX.) @ LIM pin=H Charge Termination Voltage : 4.2V ±0.7% Trickle Charge Voltage : 2.9V ±3% Supply Current (Stand-by) : 12μA (TYP.)

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 2.9V, 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 4.05V or less, the charge cycle automatically re-start after a delay of 1.7ms. As such, no external activation control is needed. 5/18 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. 6/18 XC6801 Series ■TEST CIRCUITS 2.
