2 / 20 page www.ti.com Different versions of the bqTINY-II offer many additional features. These include a temperature-sensor input for Dissipation Ratings ABSOLUTE MAXIMUM RATINGS (1) bq24020 ,, bq24022,, bq24023 bq24024, bq24025, bq24026 bq24027 SLUS549D – DECEMBER 2002 – REVISED MARCH 2006 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. detecting hot or cold battery packs, a power-good output (PG) indicating the presence of input power, a TTL-level charge-enable input (CE) used to disable or enable the charge process, and a TTL-level timer and taper-detect enable input (TTE) used to disable or enable the fast-charge timer and charge termination.

This is connected to the ground plane by a 2x3 via matrix. over operating free-air temperature range (unless otherwise noted) bq24020, bq24022, UNIT bq24023, bq24024 bq24025, bq24026 bq24027 Input voltage(2) AC, CE, ISET1, ISET2, OUT, PG, STAT1, STAT2, TE, TS, TTE, USB –0.3 to 7.0 V Output sink/source current STAT1, STAT2, PG 15 mA Output current TS 200 µA Output current OUT 1.5 A Operating free-air temperature range, TA –40 to 125 Junction temperature range, TJ °C Storage temperature, Tstg –65 to 150 Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds 300 (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. (2) All voltages are with respect to VSS. 2 Submit Documentation Feedback |
