These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT Input Voltage VIN –0.3 20 V PVIN –0.3 20 EN –0.3 6 BOOT –0.3 27 VSENSE –0.3 3 COMP –0.3 3 PWRGD –0.3 6 SS/TR –0.3 3 RT/CLK –0.3 6 Output Voltage BOOT-PH 0 7.5 V PH –1 20 PH 10ns Transient –3 20 Vdiff (GND to exposed thermal pad) –0.2 0.2 V Source Current RT/CLK ±100 µA PH Current Limit A Sink Current PH Current Limit A PVIN Current Limit COMP ±200 µA PWRGD –0.1 5 mA Operating Junction Temperature IOUT = 8 A –40 125 °C IOUT = 6 A –40 150 Storage temperature, 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. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±500 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT Input voltage range VIN 4.5 17 V Power stage input voltage range PVIN 1.6 17 V Output current TJ = –40°C to 125°C 0 8 A Operating junction temperature, TJ IOUT = 6 A –40 150 °C IOUT = 8 A –40 125 °C |
