8.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| VI | Input voltage on LBI | –0.3 | 3.6 | V |
| Input voltage on SW, VOUT, LBO, VBAT, SYNC, EN, FB | –0.3 | 7 | V | |
| TJ | Maximum junction temperature | –40 | 150 | °C |
| Tstg | Storage temperature range | –65 | 150 |
(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.
8.2 ESD Ratings
| MIN | MAX | UNIT | |||
|---|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) | –2000 | 2000 | V |
| Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) | –1000 | 1000 | |||
(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.
