BQ24010DRCRG4

The BQ24010DRCRG4 belonges to The bqTINY series which are highly integrated Li-Ion and Li-Pol linear charge management devices aimed to space limited portable applications. The bqTINY series provide integrated powerFET and current sensor,reverse blocking protection, high accuracy current and voltage regulation, charge status, and charge termination, in a small package.The bqTINY controls the battery of BQ24010DRCRG4 in three phases:conditioning, constant curre nt, and constant voltage.Charge is terminated based on minimum current. An internal charge timer offers a backup safety feature for charge termination. The bqTINY automatically re-starts the charge if the battery voltage falls below an internal threshold. The bqTINY automatically enters sleep mode when VCC supply is removed.

The BQ24010DRCRG4 has the following features:(1):small 3 mm * 3 mm MLP (QFN) package;(2)ideal for low-dropout designs for single-cell li-ion or Li-Pol packs in space limited applications;(3)integrated power FET and current sens or for up to 1-A charge applications;(4)reverse leakage protection prevents battery drainage;(4)integrated current and voltage regulation± 0.5% voltage regulation accuracy;(5)charge termination by minimum current and time;(6)precharge conditioning with safety timer;(7)status outputs for LED or system interface indicates charge and fault con ditions;(8)battery insertion and removal detection;(9)works with regulated and unregulated supplies.etc.

BQ24010DRCRG4 also has some outstanding absolute maximum ratings and electical characteristics.absolute maximum ratings:(1): supply voltage ranges (VCC all with respect to VSS) from -0.3 V to 18V;(2):input voltage range(all voltages are DC and with respect to VSS) is -0.3 to VCC V(IN, STAT1, STAT2, TS, PG, CE, TTE);(3)input voltage range is -0.3 VDC to 7VDC(BAT, OUT, ISET);(4):voltage difference between VCC and IN inputs(VCC-VIN) is ± 0.5 V;(5):output sink/source current STAT1, STAT2, PG 15 mAoutput current is 1.5 A(IN, OUT);(6):operating free−air temperature ranges from -40 to 125;(7):junction temperature ranges from -40 to 125;(8):storage temperature is -65 to150.electical characteristics:(1):VCC current is 0 mA min,3.5 mA typ and 5 mA max when  VCC is greater than VCC(min), STATx pin s in OFF state;(2):sleep current is 5 uA max when sum of currents into OUT and BAT pins and VCC is less than V(SLP);(3):input bias current on BAT pin is 500 nA max;(4):input current on TS pin is 1 uA max when  VI(TS) is 10 V or less than  10 V;(5):input current on CE pin is 1 A max;(6);input bias current on TTE pin is 1 uA max.(7):precharge to fast-charge transition threshold is 2.8 V min,2.95 V typ and 3.10 V max when voltage on BAT pin.etc.
