Absolute Maximum Ratings Symbol Parameter Value Unit Conditions VCC DC voltage applied on VCC relative to VSS -0.3 to 7.0 V VT DC voltage applied on any pin excluding VCC relative to VSS -0.3 to 7.0 V VT ≤ VCC + 0.3 TOPR Operating temperature 0 to +70 °C Commercial TSTG Storage temperature -40 to +70 °C Commercial TBIAS Temperature under bias -10 to +70 °C Commercial TSOLDER Soldering temperature 260 °C For 10 seconds Note: Permanent device damage may occur if Absolute Maximum Ratings are exceeded. Functional operation should be limited to the Recommended DC Operating Conditions detailed in this data sheet. Exposure to con- ditions beyond the operational limits for extended periods of time may affect device reliability. bq4287 |
