2 / 19 page bq25046 SLUSA83 – SEPTEMBER 2010 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. ORDERING INFORMATION PART NUMBER(1) VOUT(REG) VOVP VVDD3.3 MARKING bq25046DQCR 5.0 V 15 V 3.3 V OFS bq25046DQCT 5.0 V 15 V 3.3 V OFS (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI Web site at www.ti.com. ABSOLUTE MAXIMUM RATINGS (1) over operating free-air temperature range (unless otherwise noted) MIN MAX Input Voltage IN (with respect to VSS) –0.3 V 30 V Output Voltage OUT, VDD3.3, CHG, PG (with respect to VSS) –0.3 V 7 V Input voltage EN1, EN2, ISET (with respect to VSS) –0.3 V 7 V Input Current IN 1.5 A OUT 1.5 A Output Current (Continuous) VDD3.3 100 mA Output Sink Current CHG, PG 15 mA Junction temperature, TJ –40 °C 150 °C Storage temperature, TSTG –65 °C 150 °C ESD protection HBM 2 kV CDM 500 V (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.
