Lithium Ion Fast-Charge IC datasheet Docket ↓bq2054 Lithium Ion Fast-Charge IC Features General Description вћ¤ Safe charge of Lithium Ion battery packs The bq2054 Lithium Ion FastCharge IC is designed to optimize charging of lithium ion (Li-Ion) chemistry batteries. A flexible pulse-width modulation regulator allows the bq2054 to control voltage and current during charging. The regulator frequency is set by an external capacitor for design flexibility. The switch-mode design keeps power dissipation to a minimum. вћ¤ Voltage-regulated currentlimited charging вћ¤ Fast charge terminated by selectable minimum current; safety backup termination on maximum time вћ¤ Charging continuously qualified by temperature and voltage limits вћ¤ Pulse-width modulation control ideal for high-efficiency switchmode power conversion The bq2054 measures battery temperature using an external thermistor for charge qualification. Charging begins when power is applied or on battery insertion. вћ¤ Direct LED control outputs display charge status and fault conditions For safety, the bq2054 inhibits charging until the battery voltage and temperature are within con-Pin Connections Pin Names TM 1 16 LED2/DSEL ICTL 2 15 LED1 BAT 3 14 MOD VCOMP 4 13 VCC ICOMP 5 12 VSS ITERM 6 11 LCOM SNS 7 10 LED3 TS 8 9 TPWM 16-Pin Narrow DIP or SOIC figured limits.
