XC6802 Series GENERAL DESCRIPTION

XC682 Series ETR251-5b 1 Cell Li-ion Battery Linear Charger IC with Constant-Current/Constant-Voltage GENERAL DESCRIPTION The XC682 series is a constant-current/constant-voltage linear charger IC for single cell lithium-ion batteries. The XC682 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.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 1/1 out of setting charge current is supplied to the battery. With an external R SEN resistor, the charge current can be set freely up to 8mA (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.

XC682 Series OPERATIONAL EXPLANATION <Charge Cycle> If the BAT pin voltage is less than 2.9V, the charger enters trickle charge mode. In this mode, a safe battery charge is possible because approximately only 1/1 of the charge current which was set by the I SEN pin, 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 1/1 of the programmed charge current, the charge terminates. <Setting Charge Current> The charge current can be set by connecting a resistor between the I SEN pin and the V SS pin. The battery charge current, I BAT, is 1 times the current out of the I SEN pin. Therefore, the charge current, I BAT, is calculated by the following equations: I BAT = (V ISEN / R SEN ) x 1 (V ISEN = 1.V: Current sense pin voltage) However I BAT 8mA <Charge Termination> The battery charge is terminated when the charge current decreases to 1/1 of the full charging level after the battery pin voltage reaches a float voltage. An internal comparator monitors the I SEN pin voltage to detect the charge termination. When the comparator monitors the I SEN pin voltage is less than 1mV (charge termination detect) for 1ms (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 and supply current is reduced to 1 A. <Automatic Recharge> In stand-by mode battery voltage falls. When the voltage level at the battery pin drops to 4.5V or less, the charge cycle automatically re-starts after a delay of 2ms. As such, no external activation control is needed. 5/18

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 3mV. The charge will not restart until the voltage between the input pin voltage and BAT pin voltage rises more than 1mV. During the shut-down mode, the driver transistor turns off but a failure detection circuit operates, and supply current is reduced to 1 A. <Soft-Start Function> To protect against inrush current from the input to the battery, soft-start time is set in the circuit optimally (1 s, TYP.). <Manual Shut-Down> During the charge cycle, the IC can be shifted to the shut-down mode by floating the I SEN pin. For this, a drain current to the battery is reduced to less than 2 A and a shut-down current of the IC is reduced to less than 1 A. 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 I SEN 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 V IN pin even the BAT pin voltage is higher than the V IN pin voltage. 6/18
