2 / 28 page bq25050 SLUSA33 – MARCH 2010 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ORDERING INFORMATION PART NO. MARKING MEDIUM QUANTITY bq25050DQCR DAM Tape and Reel 3000 bq25050DQCT DAM Tape and Reel 250 PACKAGE DISSIPATION RATINGS TABLE PACKAGE RqJA RqJC TA < 25°C POWER DERATING FACTOR RATING ABOVE TA = 25°C 10 Pin 2mm × 3mm SON(1) 58.7°C/W(2) 3.9°C/W 1.70W 0.017W/°C (1) Maximum power dissipation is a function of TJ(max), RqJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = [TJ(max) - TA]/RqJA. (2) This data is based on using the JEDEC High-K board and the exposed die pad is connected to a Cu pad on the board. The pad is connected to the ground plane by a 2×3 via matrix. ABSOLUTE MAXIMUM RATINGS (1) over operating free-air temperature range (unless otherwise noted) VALUE / UNIT IN (with respect to VSS) –0.3 to 30 V Input Voltage CTRL, TS, CHG, BGATE (with respect to VSS) –0.3 to 7 V Output Voltage BAT, OUT, LDO, CHG, BGATE, IMON (with respect to VSS) –0.3 to 7 V Input Current (Continuous) IN 1.2 A Output Current (Continuous) BAT 1.2 A Output Current (Continuous) LDO 100 mA Output Sink Current CHG 5 mA Junction temperature, TJ –40°C to 150°C Storage temperature, TSTG –65°C to 150°C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values are with respect to the network ground terminal unless otherwise noted.
