(GND1 is for logic and GND2 is for analog.) 13 Batt SW This is used to detect mounting of battery. (It is pulled up internally) 14 Dchg SW This is used to detect the discharge SW. (It is pulled up internally) 15 Adpt SW This is used to detect adapter SW. (It is pulled up internally) 16, 17 Test1, Test2 These are Test Mode set-up terminal. (It is pulled up internally) 20 Batt + This terminal is connected to the + terminal of the battery. 21 Batt – This terminal is connected to the – terminal of the battery. 23 Batt T This terminal is connected to the temperature detecting terminal of the battery. 22 Vref2 This is the voltage reference terminal for temperature detection. 24 P.C This terminal is connected to the photo-coupler used for feedback. 25 VDET This terminal is used to monitor the output voltage. 26, 30 CP1, CP2 This terminal is used to make connection with capacitor(s) and resistor(s) which are used for phase compensation. 29 IDET This terminal is used to detect the charging current or output current. 31 PCS IN This is an input terminal used for photo-coupler short. 32 PCS OUT This terminal goes "H" when over-current is detected. 33 OCSET This terminal is used to set the over-current detection value when the adapter mode is used. 34, 35 Iset1, Iset2 These are used to set the charging current. (Iset1 is for quick charge and Iset2 is for the trickle charge.) 36 Vref1 This terminal is sets the standard voltage for over-current set-up value and the charge current set-up. |
