... For a value of 110K, the Low Current is 92mA. SD Shutdown – A logic high places the LX2206 in sleep mode; can also be used for USB suspend. Charging status logic pin and LED driver – This pin can source or sink 10mA of current to drive an external LED in either output state. This pin is low (current sinking mode) when the battery is in charging mode and becomes STAT high (current sourcing mode) when the charge cycle is finished ...

... ERMINATION ODE To increase system battery life and avoid float charging, the LX2206 turns off the pass element once the battery has been fully charged. The charge termination state occurs at the end of constant voltage mode. The termination current is set by the value of the resistor connected to the HCP programming pin ...

... PCB to provide a good conduction path for heat. This insures the LX2206 stays cool and can provide the maximum charge current to minimize the time required to charge the battery. For stability purposes and to reduce voltage switching transients it is important to place capacitors close to the IN and BAT pins. A 10µ ...

... T M ATTERY EMPERATURE ONITOR The LX2206 has an input to monitor the battery temperature during battery charging; this method assumes the battery pack contains a thermistor expressly for this purpose. A typical Lithium ion battery should only be charged from a range of 0°C to 60°C. For this calculation, a Vishay NTHS0402N01N1003J Thermistor was used. This thermistor is 327KΩ ...

... NPUT OWER In order to detect when the input power source has been removed, the LX2206 requires that a small current (up to 200uA) momentarily flow out of the IN pin (in the reverse direction). Once detected, the reverse IN current is shut off (the IN pin becomes a very high impedance until an input power source is later reapplied) ...
