6.1 Absolute Maximum Ratings
over operating free-air temperature range unless otherwise noted(1)| MIN | MAX | UNIT | |
|---|---|---|---|
| Input voltage on VAC pin with respect to AGND | 20 | V | |
| Input voltage range on all other pins except AGND/PGND pins with respect to AGND | –0.3 | 7 | V |
| Current at AC, VBAT, VINMAIN, L1, PGND1 | 1800 | mA | |
| Peak current at all other pins | 1000 | mA | |

| Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds | 260 | °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.
6.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. Pins listed as ±1000 V may actually have higher performance.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. Pins listed as ±1000 V may actually have higher performance.
