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. 8 Specifications 8.1 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX VALUE Voltage range (with respect to GND) VBUS (converter not switching) –2 22 V PMID (converter not switching) –0.3 22 V STAT –0.3 20 V PG (bq25892) –0.3 7 V DSEL (bq25890) –0.3 20 V BTST –0.3 20 V SW –2 16 V BAT, SYS (converter not switching) –0.3 6 V SDA, SCL, INT, OTG, REGN, TS, CE, QON –0.3 7 V PSEL (bq25892) –0.3 7 V D+, D– (bq25890) –0.3 7 V BTST TO SW –0.3 7 V PGND to GND –0.3 0.3 V ILIM –0.3 5 V Output sink current INT, STAT 6 mA PG (bq25892) 6 mA DSEL (bq25890) 6 mA Junction temperature –40 150 °C Storage temperature range, Tstg –65 150 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 8.2 ESD Ratings VALUE UNIT VESD Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) ±2000 V Charged device model (CDM), per JEDEC specification JESD22-C101(2) ±250 V (1) The inherent switching noise voltage spikes should not exceed the absolute maximum rating on either the BTST or SW pins. A tight layout minimizes switching noise. 8.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT VIN Input voltage 3.9 14(1) V IIN Input current (VBUS) 3.25 A ISYS Output current (SW) 5 A VBAT Battery voltage 4.608 V IBAT Fast charging current 5 A Discharging current with internal MOSFET Up to 6 (continuos) A 9 (peak) (Up to 1 sec duration) A TA Operating free-air temperature range –40 85 °C |
