Description

The BQ24100RHLR is one member of the BQ24100 series.The bqSWITCHER(TM) series are highly integrated Li-ion and Li-polymer switch-mode charge management devices targeted at a wide range of portable applications. The bqSWITCHER(TM) series offers integrated synchronous PWM controller and power FETs, high-accuracy current of BQ24100RHLR and voltage regulation, charge preconditioning, charge status, and charge termination, in a small, thermally enhanced QFN package.The system-controlled version provides additional inputs of BQ24100RHLR for full charge management under system control.

Features of the BQ24100RHLR are:(1)ideal for highly efficient charger designs for single-, two- or three-cell li-ion and li-polymer battery packs; (2)integrated synchronous fixed-frequency pwm controller operating at 1.1 MHz With 0% to 100% duty cycle; (3)integrated power FETs for up to 2-A charge rate; (4)high-accuracy voltage and current regulation; (5)available in both stand-alone (built-in charge management and control) and system-controlled (under system command) versions; (6)status outputs for LED or Host processor interface indicates charge-in-progress,charge completion, fault, and ac-adapter present conditions; (7)20-V maximum voltage rating on IN and OUT pins; (8)high-side current sensing; (9)optional battery temperature monitoring; (10)automatic sleep mode for low power consumption; (11)system-controlled version can be used In NiMH and NiCd applications; (12)uses ceramic capacitors; (13)reverse leakage protection prevents battery drainage; (14)thermal shutdown and protection; (15)built-in battery detection.

The absolute maximum ratings of the BQ24100RHLR can be summarized as:(1)junction temperature range:-40 to 125;(2)storage temperature:-65 to 150(3)operating free-air temperature range:-40 to 85;(4)supply voltage range:20V;(5)input voltage range Vout:-0.7 to 20V;(6)output sink:10mA.The voltage regulation feedback occurs through the BAT pin. This input is tied directly to the positive side of the battery pack.The bqSWITCHER monitors the battery-pack voltage between the BAT and VSS pins.The bqSWITCHER is offered in two fixed-voltage versions: 4.2 V and 8.4 V as selected by the CELLS input. A low or floating input on the CELLS selects single-cell mode (4.2 V) while a high-input selects two-cell mode.For device options that include adjustable output voltage, the voltage regulation feedback is through the FB pin.A resistor divider is used from the battery output voltage to GND. The BAT pin remains connected directly to the battery output voltage for current sensing with respect to SNS.
