XC6802 Series 800mA 1 Cell Li-ion and Li-Po Battery Linear Charger IC with Constant-Current/Constant-Voltage

GENERAL DESCRIPTION The XC6802 series is a constant-current/constant-voltage linear charger IC for single cell Lithium-ion and Lithium polymer batteries.The XC6802 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. With an external RSEN resistor, the charge 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

<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 ISEN pin, is supplied to 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 ISEN pin and the VSS pin. The battery charge current, IBAT, is 1000 times the current out of the ISEN pin. Therefore, the charge current, IBAT, is calculated by the following equations: IBAT = (VISEN / RSEN) x 1000 (VISEN = 1.0V (TYP.): Current sense pin voltage) However IBAT≦800mA (SOT-25, SOT-89-5, and USP-6C), IBAT≦500mA (USP-6EL) <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 monitors the ISEN pin voltage is less than 100mV (charge termination detect) (*1) for 1ms TYP. (charge 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: ISEN pin voltage should be less than 100mV. <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/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 the VSS, a trickle charge mode starts to operate for protecting 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 more than the UVLO voltage. 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 ISEN pin. For this, a drain current to the 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 keeping the ISEN pin in H level. <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 the BAT pin voltage is higher than the VIN pin voltage.

1. Please note that in cases where the charge current is less than 100mA, there is a possibility that the trickle charge and the

detection of charge completion may not function correctly. 2. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be

exceeded. 3. 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. 4. 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.
