    Lithium Ion Fast-Charge IC
    Features General Description ➤ 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. ➤ Voltage-regulated currentlimited charging
    ➤ Fast charge terminated by selectable minimum current; safety
    backup termination on maximum
    time
    ➤ Charging continuously qualified
    by temperature and voltage limits
    ➤ 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. ➤ 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
