1/21 xc6802 series 800ma single cell li-ion battery linear charger ic general description the xc6802 series is a constant-current/constant-voltage linear charger ic for single cell lithium-ion batteries. the xc6802 includes a reference voltage source, battery voltage monitor, dr iver transistor, constant-curren t/constant-voltage charge circu it, over heat protection circuit, phase compensation circuit. the ba ttery 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 charge to a battery is possible because approximately 1/10 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 800ma (max.), therefore, the series is ideal for vari ous battery charge applications. the seri es? charge status output pin, /chg pin, is ca pable of checking the ic?s charging state while connecting with an external led. a pplications ? ? charging docks, charging cradles ? ? mp3 players, portable audio players ? ? cellular phones, pdas ? ? bluetooth headsets ? features operating voltage range : 4.25v ~ 6.0v charge current : external ly set up to 800ma (max.) charge termination voltage : 4.2v ? 0.7% trickle charge voltage : 2.9v ? 3% supply current (stand-by) : 15 a (typ.) function : constant-current/constant-voltage operation thermal shutdown automatic recharge charge status output pin soft-start function (inrush limit current) operating ambient temperature : -40 ?? +85 ? packages : sot-89-5, sot-25, usp-6c, usp-6el environmentally friendly : eu rohs compliant, pb free typical application circuit etr2501-006 typical performance characteristics ? battery charge cycle li-ion battery charge cycle 0 100 200 300 400 500 600 700 0.00 0.25 0.50 0.75 1.00 1.25 1.50 1.75 2.00 time (hours) charge current i bat (ma) 3.00 3.20 3.40 3.60 3.80 4.00 4.20 4.40 battery voltage v bat (v) vin=5.0v, cin=1uf rsen=2kohm , 830mah batter y charge current battery voltage vin=5.0v, cin=1 f rsen=2k ? , 830mah battery li-ion battery charge cycle batter y volta g e charge current charge current : i bat (ma) battery voltage : v bat (v) time ( hour )
